Construction of high-voltage cables for quality reasons because the quality of construction led to instances of high-voltage cable system failures, many Yulin high voltage power cables, mainly due to the following aspects: First, the relatively poor field conditions, cables and connectors in the factory manufacturing environment and process requirements are very high , and the construction site temperature, humidity, dust is not well controlled. Second, the cable insulation surface in the construction process will inevitably leave tiny slip marks, semi-conductive particles and sand on Shabu is also possible to embed high-voltage power cable insulation in Hanzhong, in addition to the joint construction process due to exposure to air insulated high-voltage power cables, insulation will also inhale water Weinan high-voltage power cables, which gave long-term safe operation of the stay hidden. Third, when the installation is not in strict accordance with the provisions of the construction process or process does not take into account the problems that may arise. Fourth, the final acceptance test DC voltage caused by an electric field formed in the joint anti-cause dielectric breakdown. Fifth, because of poor management led sealed. Intermediate copper joints must be sealed enclosure plus PE or PVC insulation coating structure, to ensure that seals are dense in the construction site, so effectively ensure the sealing waterproof connector. High voltage power cables high voltage power cable laying 1. laying indoors, tunnels and pipelines --VY, VLY Cable: PVC insulated cable can not bear external mechanical forces. 2. laying indoors, in tunnels and direct soil --VV22 VLV22 VV23 VLV23 Cable: PVC insulated PE sheathed power cable cable can withstand external mechanical forces. 3. laying high drop area --VV32 VLV32 VV33 VLV33 VV42 VLV42 VV43 VLV43: PVC insulated, sheathed steel wire armored power cable - the cable can withstand external mechanical forces and considerable tension. 4. laying indoors, tunnels and pipelines YJV YJLV: XLPE insulated PVC, PE sheathed power cables - can not bear external mechanical forces. 5. laying indoors, in tunnels and direct soil --YJV22 YJLV22 YJV23 YJLV23: XLPE insulation PVC, polyethylene sheathed power cable - the cable can withstand external mechanical forces. 6. laying high drop area --YJV32 YJLV32 YJV33 YJLV33 YJV42 YJLV42 YJV43 YJLV43: XLPE insulation PVC, PE sheathed steel wire armored power cables - can withstand external mechanical forces and considerable tension.
