a. Good grip and firm fixed line. b, Energy-saving design, line loss is small. c, Good insulation, no damage to the wire. d. Easy installation and simple maintenance. e, Compact structure, beautiful appearance.Busbar fittings are divided into soft busbar fittings and hard busbar fittings (general term for fixing and hanging hard busbar accessories), busbar spacers (supports that maintain a certain interval between hard busbar sheets). Soft busbar fittings are mostly used outdoors, with large outdoor space, wide wire spacing, good heat dissipation effect, convenient construction and low market price. Hard busbar fittings can be divided into rectangular busbars, grooved busbars, tubular busbars and so on according to their shapes. The stereotyped flat outdoor rectangular busbar fixing hardware is a frame-type fitting composed of a base plate made of south steel plate, an aluminum alloy cover plate and fasteners. The cover plate is made of pin alloy to eliminate hysteresis losses. The vertical outdoor rectangular busbar fixing metal has two aluminum alloy splint-type columns to clamp the busbar, and the metal fitting also has the performance of eliminating hysteresis loss. In addition to the rectangular busbar fixing fittings, there are also rectangular busbar standing fixing fittings, which are made of a steel plate with a bottom plate, two long bolts and an aluminum alloy cover plate to form a frame bolt. In order to reduce the gap between the busbar and the bolt and improve the rigidity, a seamless steel pipe is sleeved on it. Rectangular busbar vertical fixed fittings are also divided into indoor and outdoor types.
