Insulation shield tube superiority of a bus, tube-shaped bus bar insulation shield has the following advantages a) carrying capacity of the bus for bassoon-shaped hollow conductor, the conductor surface is circular surface, surface area, surface current density conductor evenly distributed, the maximum rated current can be up to 12000A. b) electrical insulation properties and strong tubular busbars way sealed shield insulation, shell ground bit is zero, the bus surface electric field distribution, strong electrical insulation properties, can be directly through the cable trench and cable dissection. c) the skin effect is low, power loss is small tubular busbars low coefficient of skin effect, kf ≦ 1, AC resistance is small, and therefore little power loss bus, greatly enhance the conductivity of the bus. d) cooling conditions, low temperature rise as a hollow tubular bus conductors, bus inner diameter of the duct can be naturally formed hot air convection cooling conditions are better compared to the conventional rectangular bus. e) the allowable stress [σ] large span, high mechanical strength we "conductive material Electrical Manual" can be learned, stress brass is 294MPa, a tensile strength of 320MPa, a full rectangular copper busbar 4 times, so that the cross-linked shield insulated copper busbars can withstand short-circuit power is far greater than the rectangular bus. Brass busbar largest span can reach 9 m, if the double steel structure supporting the adoption of its largest span can reach 14 meters, with direct access to the high-pressure chamber and switchgear or reactor connected to a corresponding reduction in the post insulators, bus fittings and civil architecture base, plus the bus using steel structural support, which has a strong anti-vibration capability. f) electrical insulation performance, high stability master insulation material insulation shield insulated copper busbar insulation structure is formed by an alternating multiple insulation and shielding materials, the potential from the inside and the outside layer by layer decreases, until the surface potential 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 . h) bus architecture concise, clear layout, easy installation, low maintenance. i) the product once installation, maintenance-free life.
