If you are looking for a single cable that will give you the fastest possible charge at any charging point, there are three things you must know: That you need a Mode 3 cable, what if your car has a Type 1 or Type 2 inlet, and the capacity of its onboard charger.
The very first thing you should know is that if you havent already, you should install a home charger. Home chargers are available with fixed cables and with outlets. No matter what you choose, you will need a cable for charging away from home. Read more about why you should install a home charger here.
The Mode system goes from 1 to 4, but what you want is a Mode 3 charging cable. Mode 3 chargers are the standard for EV charging and can be used at any publically available charging point.
In the world of EV cables, Type refers to the design of the vehicle side plug, which can be either a Type 1 or Type 2. These correspond to Type 1 and Type 2 vehicle inlets. A Type 2 charging cable is the current standard. If you have a relatively new car, this is most likely what you have. Type 1 inlets can be found on older models of Asian brands, such as the Nissan Leaf . If in doubt, make sure to check the inlet on your car.
Getting right amps, kilowatts, and knowing if you need a 1-phase or 3-phase cable is often what new EV owners find most challenging. Fortunately, there is an easy way to make the right choice. If youre looking for a cable that will give you the fastest possible charge at any charge point, all you have to know is the capacity of your onboard charger. Use the table below to select a cable with a kW rating equal to or higher than the capacity of your onboard charger. Note that 3-phase cables can also use 1-phase.

If you only plan to use the cable at home, you may also want to consider the kW output capacity of your home charger. If the capacity of the home charger is lower than that of your car, you can use the table above to choose a cheaper and lighter cable with the right specification. If it can only charge at 3,6 kW, there is little point in having a 32 amp / 22 kW EV charging cable, at least until you buy a new car.
EV charging cables are available in different lengths, usually between 4 to 10m. A longer cable gives you more flexibility, but also heavier, more cumbersome and more expensive. Unless you know you need the extra length, a shorter cable will usually suffice.
All EV charging cables are not the same. There are several significant differences between high-quality and low-quality cables. Higher-quality cables are more durable, are made with better materials and stronger protections against the strains expected from everyday use.
Quality cables are also better suited for extreme conditions. One thing many cable owners will have noticed is that the cable becomes stiff and unwieldy when the temperature drops. Higher-end cables are designed to remain flexible even in severe cold, making them easier to use and stow away.
Water getting on to the terminals and into the vehicle inlet is another common problem that may cause corrosion and a poor connection over time. One way to help avoid this issue is to select a cable with a cap that doesnt collect water and dirt when the cable is in use.
High-end cables usually also have a more ergonomic design and a better grip. For something you may use every day, usability is worth considering.
Even the most durable charging cable must be replaced in the end. When that happens, every component should be fully recycled. Unfortunately, most EV charging cable plugs are water- and impact-proofed through with a process called potting, which involves filling the interior of the plug with plastic, rubber, or resin compound. These compounds make it nearly impossible to separate and recycle the components later. Fortunately, there are cables made without potting and reusable materials that can be completely recycled after use.
Without a bracket, strap, or bag, an EV charging cable can be difficult to store and transport tidily and safely. At home, being able to coil and hang up the cable will help you keep it out of the way and protect it from water, dirt, and being run over by accident. In the car, a bag that can be fixed in the trunk helps keep the cable stowed away and not moving during driving.
An EV charging cable is also relatively expensive and a tempting target for burglars. A lockable docking and storage unit helps you protect your cable from being stolen, while also keeping it away from the floor.
In short, this is what you have to know:
What is Insulated Wire?
Insulated wire or cable consists of a non-conductive material resistant to an electric current. It surrounds and protects the wire or cable inside.
What Are The Benefits of Insulated Wire?
The obvious benefit of insulated wire is the color. While this may seem simple, its very important, especially in sophisticated wire and cable applications. Colored insulation can help you determine the difference between wires when there are many running together. Designated wires for different applications can help the wired network remain organized.
Wires that are insulated are also corrosion and crush resistant. Ensuring your wire will last is essential to the longevity of your installation.

What Causes Wire to Corrode?
Chemical exposure, environmental pressure, weather, and flexibility issues can cause the wire to corrode.
Chemicals For many household appliances and underground cable applications, there are harmful chemicals.
Luckily, Performance Wire & Cable offers HALAR cathodic protection cable. This insulated wire is highly resistant to chlorine, hydrogen gases, and other chemicals that lead to corrosion. HALAR wire is commonly used directly in water and damp environments because of its properties.
KYNAR insulated cables are also a good choice if youre looking for chemical resistance.
Weather There are insulated wires explicitly made to perform in high temperatures and those best suited for very fridged temperatures. Cross-linked polyethylene, also known as XLPE cables, are perfect for these types of applications. Additionally, insulated wire offers protection against wetness.
Flexibility If a cable is going to be bent frequently, it must have proper insulation to give it freedom of motion. If not, the wire will not last.
Pressure Its no secret that wires are also commonly used underground. There can be an incredible amount of pressure on the wire from the weight of the earth above it. To maintain maximum performance, wires cannot succumb to being crushed.
HMWPE cathodic protection cables provide outstanding resistance to crushing and pressure. The wire insulation is a high molecular weight polyethylene material protecting your copper cables.
Why Choose Insulated Wire?
Not only is insulated wire corrosion-resistant, but it is also cost-effective. Its better to buy insulated wire than wire that needs to be repaired or replaced. Replacement or repair of wire will lead to service disruption and cost, which is not ideal.
Safety is essential in wiring applications. Wires carry current that can cause electric shock when touched or cause electrical explosions, shorted wire systems, and more. Insulated wire is the safest choice.
Insulated Wire, Whats Protecting Your Cable?
There are varieties of available insulations for wire and cable. Insulated wire or cable is coated with a non-conductive material that is resistant to an electric current, which surrounds and protects the wire and cable inside.
Cable and wire insulation prevents the wires current from coming into contact with other conductors, it preserves the wire material against environmental threats and resists electrical leakage. There are three major categories of wire insulation, each with a variety of styles. These include plastic, fluoropolymers, and rubber.
This is an inexpensive and easy-to-use material. This type of wire insulation can be used in diverse applications. The temperature range is -55°C to 105°C and it is flame, moisture, and abrasion-resistant. PVC insulated wire holds up against gasoline, ozone, acids, and solvents and is safe for medical and food-related purposes as it is odorless, tasteless, and non-toxic.
Semi-Rigid PVC (SR-PVC)A form of PVC cable insulation, this is mainly used as primary insulation and is very abrasion-resistant. Semi-rigid PVC is resistant to heat, water, acid, and alkali, as well as being flame-retardant.Plenum Polyvinyl Chloride (Plenum PVC)Plenum PVC, yet another polyvinyl chloride wire insulation material, is great for use in building spaces behind dropped ceilings or raised floors, which are left open to allow for air circulation.Polyethylene (PE) This wire insulation compound is used most on coaxial and low capacitance cables. It carries exemplary electric qualities, although it is flammable. Many times, this cable insulation is used in certain applications because it is affordable and can reduce the dielectric constant, making it an attractive option for cables requiring high-speed transmission. Polyethylene can also be cross-linked to produce high resistance to cracking, cut-through, soldering, and solvents. PE can be used in temperatures ranging anywhere from -65°C to 80°C. All densities of Polyethylene are stiff, hard, and inflexible. Performance Wire and Cable offers HMWPE as popular insulation for products.Polypropylene (PP)Very similar to polyethylene, polypropylene has a wider temperature range of 30°C to 80°C. This wire insulation is used primarily within thin walls.Polyurethane (PUR) From extremely low to very high temperatures, polyurethane is known for its extreme toughness, flexibility, and flex life. Because of the excellent ratings for chemical, water, and abrasion resistance, this material works well in retractile cord applications and can be a good option for salt-spray and low-temperature military purposes.Chlorinated Polyethylene (CPE)Commonly found in power and control cables as well as industrial power plant applications, CPE cable insulation displays very good heat, oil, and weather resistance. More times than not, CPE serves as a lower cost and more environmentally friendly alternative to chlorosulfonated polyethylene.NylonNylon, very flexible wire insulation, is usually extruded over softer insulation compounds. It serves as a tough insulation, exhibiting strong abrasion, cut-through, and chemical resistance.
