Model No.: VLBJ
At present, China has a lot of Power Distribution network using a neutral point resistance grounding runs. After installing the neutral grounding resistor cabinet, when the occurrence of non-metallic grounded affected ground resistance, and the current flowing through the ground than the neutral point earthed metallic significantly reduced, while the sound phase voltage rises too significantly reduced, zero- sequence voltage value is about half of the single-phase metallic grounded. Thus, the use of resistance grounded neutral point, single-phase ground can be reduced when transient over-voltage and over-voltage arc grounding eliminate some resonance over-voltage, and can use a simple protection devices quickly select the fault line, cut point of failure.
WE has developed excellent technical team and sophisticated equipment, specializing in the development and distribution system neutral grounding series of products, production, sales and service work. Development and production of neutral grounding resistor cabinet for 6 ~ 35kV cable lines to the city -based distribution network, a large industrial enterprises, factories, airports, ports, subways and other major electricity distribution network users, as well as coal enterprises 0.66KV, power Plant electricity 0.4KV, 6KV, 10KV system
