MNL indoor rectangular busbar fixing fittings are used for fixing, suspending and supporting power distribution devices. They are called busbar fittings. They are divided into soft busbar fittings and hard busbar fittings (general term for fixing and hanging hard busbar accessories), busbar spacers (maintaining hard busbars) Supports that define the spacing between the busbars). 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. In order to keep the distance between the soft busbar and its downconductor unchanged and the two wires do not collide, the MNL indoor rectangular busbar fixing fittings are installed with spacer clips on the soft busbar in the span and downconductor. The installation distance of spacer clips is determined by design. The spacer clip is made of aluminum alloy to eliminate hysteresis loss and corona loss. The spacer clamp made of aluminum alloy not only reduces the quality of the clamp, but also helps to reduce the load of the busbar. Soft busbar fixing fittings MNL indoor rectangular busbar fixing fittings are divided into two types: single wire and double wire. The soft busbar fixing hardware made of aluminum alloy is fixed on the single or double tension insulator string by two tension clamps through the flexible busbar with the connecting plate. The MNL indoor rectangular busbar fixing hardware is suitable for power plants, substations and various Fixation of soft busbars on post insulators in a power distribution device. MNL type indoor vertical busbar fixing hardware, suitable for vertical busbar arrangement, installed on the pillar insulator with a single hole of M10mm or M16mm, to fix one to three pieces, the specifications are 3mm × 6.3mm ~ 125mm × 12.5 mm rectangular hard busbars. Outdoor rectangular busbar fixing fittings The flat laying outdoor rectangular busbar fixing fittings are frame-type fittings composed of a base plate made of south steel plate, an aluminum alloy cover plate and fasteners. The cover is made of pin alloy to eliminate hysteresis losses. The vertical outdoor rectangular busbar fixing metal has two aluminum alloy plywood-type columns to clamp the busbar, and the hardware also has the performance of canceling the 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.
