High voltage wire

High-voltage cable is a type of power cable, which refers to a power cable used to transmit between 10kv-35kv (1kv=1000v), and is mostly used in the main road of power transmission. The product implementation standards for high-voltage cables are gb/t 12706.2-2008 and gb/t 12706.3-2008

Types of high-voltage cables

The main types of high-voltage cables are yjv cable, vv cable, yjlv cable, and vlv cable.

yjv cable full name XLPE insulated PVC sheathed power cable (copper core)

The full name of vv cable is PVC insulated and sheathed power cable (copper core)

yjlv cable full name XLPE insulated PVC sheathed aluminum core power cable

VLV cable full name PVC insulated PVC sheathed aluminum core power cable

Due to the excellent electrical conductivity of copper conductors, more and more projects use copper core power cables as the main road of the power supply system, while aluminum core power cables are less used, especially in the higher-voltage power system, choose copper core The more cables there are.

The structure of high-voltage cables

The components of a high-voltage cable from the inside to the outside include: conductor, insulation, inner sheath, filler (armor), and outer insulation. Of course, armored high-voltage cables are mainly used for underground burying, which can resist high-strength compression on the ground and prevent damage from other external forces.

High voltage cable use characteristics

This product is suitable for AC rated voltage 35kv and below for power transmission and distribution. The maximum long-term working temperature of the cable conductor is 90 degrees, and the maximum temperature of the cable conductor does not exceed 250 degrees when short-circuited (the longest time does not exceed 5s).

UHV cable

1kv and below are low voltage cables; 1kv~10kv are medium voltage cables; 10kv~35kv are high voltage cables; 35~220kv are UHV cables;

UHV cable is a kind of power cable that has emerged with the continuous development of cable technology. UHV cable is generally used as a central hub in large-scale power transmission systems. It is a high-voltage cable with high technical content and is mainly used for long-distance power transmission.

Causes of high-voltage cable failure

The cable is the bridge between the power supply equipment and the electrical equipment, and plays the role of transmitting electric energy. It is widely used, so failures often occur. The following is a brief analysis of the causes of common problems of high-voltage cables. According to the causes of failures, they are roughly divided into the following categories: manufacturer manufacturing reasons, construction quality reasons, design units design reasons, external force damage Four categories.
