Zibo 35kv brass bus manufacturers an insulating tube bus production process of the product should be used to clean production processes fully automated intelligent production, its wide versatility, beautiful appearance, practical. Product sealed multilayer insulation shield manner, a plurality of metal capacitive screen between the insulating layer, so that each layer by layer to reduce the potential of the insulating layer until the zero potential, and increase the equalizing protection measures within each of the insulating layer so that a uniform electric field, reduce the amount of partial discharge, greatly extending the aging time of insulating materials; insulating tube bus with natural cooling function (two-port bus mouth breathing, air can flow in the pipe), to ensure safe and reliable operation of the bus. Shield insulated copper bus bar insulation is an insulation structure formed by alternating multiple insulation and shielding materials, potential decreased from the inside and the outside layer by layer, until the surface potential is zero. Multiple shield ensuring uniform charge distribution on each surface of the insulating layer, an insulating layer surface to avoid the partial discharge, and interference from other electric and magnetic phase bus, plus the main insulation material PTFE has excellent The electrical properties and chemical stability, low dielectric loss, flame retardant, anti-aging, long service life. f) ability of anti-electrical shock can be used directly with the bus-specific gold tubular steel frame fixed on the bus or on a concrete stand, canceled wall bushing and post insulators, has strong anti-vibration capability. g) from environmental interference, reliability executives shaped busbar per phase is sealed shield insulation, no internal condensation generated, and the elimination of external moisture, dust and foreign objects caused by the ground and phase fault, running with a highly reliable .
