CKX6 air insulated bus bar channels
The bus bar channels series product rated voltage 400 V and 690 V and 1000 V rated voltage insulation, frequency 50 Hz ac ~ 60 Hz, rated current 200 ~ 6300 A three-phase three-wire, three-phase four-wire, three-phase five wire transmission and distribution system, mainly as A mining, enterprises, institutions and high-rise buildings in the new power distribution equipment, installation and use of countless user process has proved it is A kind of very good power supply equipment.
The product has small volume, transmission capacity, overload ability strong, flexible circuit expands, beautiful appearance, compact structure, easy installation and maintenance, effectively prevent the fire has advantages such as stable performance, safety and reliability prominent characteristics. Adapted to the equipment dense, branch more places, with great flexibility and distribution of high efficiency, it can completely replace the traditional cable transmission and distribution mode.
Shell plate electrostatic spray, aluminum plate surface conductive oxidation or stainless steel sheet, and corrosion resistance is strong, insulation performance is good, dielectric strength, high impedance is low, the electric power, the continuity of the ground protection less reliable, excellent heat dissipation, high mechanical strength.
