Overhead insulated conductors clarify:
High-voltage cable is a kind of power cable , which refers to the power cable used for transmission between 10KV-35KV (1KV = 1000V), which is mostly used for the main road of power transmission. The commercial product specification for high-voltage cables is GB12706.3-2002
Varieties of high-voltage cables
The secondary varieties of high-voltage cables are YJV cables, VV cables, YJLV cables, and VLV cables.
YJV cable full name XLPE insulated PVC sheathed power cable (copper core)
VV cable full name PVC insulated PVC 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 conductive function of copper conductors, more and more projects use copper core power cables as the main road for power supply fragmentation, while aluminum core power cables use less, especially in higher voltage power fragmentation. The more cables there are.
Construction of high-voltage cables
The components of the high-voltage cable from the inside to the outside include: conductor, insulation, inner sheath, filler (armoring), and outer insulation. Of course, armored high-voltage cables are mainly used for burial, which can resist high-intensity squeezing in the air, while avoiding damage by other external forces.
High-voltage cable operating characteristics
This product is suitable for fixed additional installation of power transmission and distribution with AC additional voltage of 35KV and below. The high temporary task temperature of the cable conductor is 90 degrees. When short circuit (long time does not exceed 5S), the low temperature of the cable conductor does not exceed 250 degrees.
1KV and below are high voltage cables; 1KV ~ 10KV are medium voltage cables; 10KV ~ 35KV are high voltage cables; 35 ~ 220KV are extra high voltage cables;
UHV cable is a kind of power cable that appears with the development of cable technology from time to time. UHV cable is generally used as a central link in large-scale power transmission systems. It belongs to a high-tech cable with high technical content, and is mainly used for remotely spaced Power transmission.
