What type of cable should be used for the charging gun cable?

With the popularization of electric vehicles and the continuous improvement of charging pile infrastructure, the charging gun cable, as a crucial part connecting the charging pile and the electric vehicle, has become increasingly important. The quality of the charging gun cable is directly related to the safety and efficiency of charging. Therefore, we need to select the appropriate type of charging gun cable.

1. Basic requirements for the charging gun cable

The basic function of the charging gun cable is to transmit electrical energy, so it needs to have good electrical conductivity, high-temperature resistance, wear resistance, corrosion resistance, etc. At the same time, the cable type of the charging gun cable needs to comply with national standards. For example, currently, the main cables on the market conform to standards such as IEC 62196 and GB/T 20234. These standards specify the types of charging interfaces, current-carrying capacity, requirements for insulating materials, etc., making the charging process safer and more reliable.

2. Common types of cables for charging gun cables

Among many types of cables, there are several common cables that are particularly suitable for use as charging gun cables.

RVV cable

It is suitable for charging electric vehicles. Its flexible design is more suitable for frequent bending and moving, and it can withstand a large current.

TRVV drag chain cable

This cable is specifically designed for motors and mobile devices. It has good wear resistance and is suitable for use in harsh environments.

PUR cable

The chemical resistance and wear resistance of polyurethane cables are very useful in outdoor and industrial environments.

3. Selection of cable materials

The selection of materials for the charging gun cable is also a key factor in ensuring its performance. There are many common materials for our charging gun cables.

Copper wire

It has excellent electrical conductivity. Oxygen-free copper or tinned copper is used to improve its corrosion resistance.

Polyvinyl chloride (PVC)

As an insulating material, it has strong toughness and low cost, and is suitable for use in various environments.

Polyurethane (PU)

Although the cost is relatively high, it can better withstand high temperatures and chemical corrosion in industrial environments, extending the service life of the cable.

4. Details for purchasing charging gun cables

Current load capacity

Different charging gun cables have different current load capacities. When selecting, choose the appropriate type according to the power of the charging pile to avoid potential safety hazards caused by current overload.

Temperature resistance performance

Especially in high-temperature environments, the temperature resistance performance of the charging gun cable directly affects its service time and lifespan. Therefore, we should select cables made of high-temperature-resistant materials.

Compatibility of connectors

The interface designs of different charging piles and charging guns are different. Therefore, it is necessary to confirm the compatibility of the interfaces before purchasing.
