Ningbo Qiaopu Electric Co., Ltd. teach you to deal with the problem of high voltage power lines

The Ningbo Qiaopu Electric Co., Ltd. is specialized in producing power cord manufacturers full range of power line, low-voltage power lines, high voltage power lines, high voltage power lines. Production of high-voltage power line such as Ningbo Qiaopu Electric Co., Ltd. factory 6kV or 10kV electrical equipment installation, there will always encounter a single-core short power cord for the cable. Electrical installation of the works, sometimes three core high-voltage power lines, the skin stripped, and then stripped ladle armored single-core power cord to take three core lines. Single-core power cord insulation resistance to meet the requirements, install the wire core from the outer metal components to close, will also appear the phenomenon of the discharge structure, wet weather in the spring, this phenomenon would endanger the equipment and personal safety. A factory such as high-pressure oven 720kW motor to start the resistance of resistor used in liquid, high-voltage cabinet mounted on the third floor, liquid resistance installed in the high-voltage cabinet below the second floor Ningbo Qiaopu Electric Co., Ltd. power cord compartment. Electrical conducting connection between the high voltage cabinet with three-phase liquid resistance, using a high voltage power lines in three-core wire, the transmission the wire insulation epidermis (in the hole near the floor the power cord) on the air discharge phenomenon. I saw the arc flash, dth sound very scary.
Ningbo Qiaopu Electric Co., Ltd. from the electromagnetic field theory can be seen: the distributed capacitance of three-wire power cord three-phase balance, the ground shield surrounded, there is no external electric field exists only within the electric field, the energy transfer can only be carried out in-house, will not leakage. Shielded high-voltage insulated wire distributed capacitance is more complicated, but most likely to produce the discharge from the largest wire grounding capacitance.
