Problems solved by technology

The disadvantage of this kind of distribution box is that the insulation performance is not good, and it will cause serious safety hazards when the line is short-circuited, and the product is relatively heavy and inconvenient to install.
In recent years, plastic distribution box shells have been developed, which have good insulation properti

Abstract

The invention belongs to the field of electric distribution material, and discloses an electric distribution box outer shell material prepared from the following raw materials: kaolin, glass fiber, tetraethyl orthosilicate, butyl acetate, aluminum tripolyphosphate, antimony trioxide, diethylene glycol monobutyl ether, isobutanol, polycarbonate, glycerol monostearate, quartz sand, phenolic resin, borax, silicon carbide and acrylic resin. While effectively maintaining relatively good insulation performance, the electric distribution box outer shell material has mechanical properties, thermal properties and flame retardance improved greatly, and can effectively prevent electric shock; and moreover, produced heat is easy to discharge, so as to avoid potential safety hazards caused by high temperatures of an electric distribution box.

Description

[0001] technical field [0002] The invention belongs to the field of distribution materials, and in particular relates to a distribution box shell material and its application. [0003] Background technique [0004] The distribution box is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then the low-voltage side of the transformer is stepped down to lead to low-voltage The distribution box and the low-voltage distribution box are connected to each power distribution panel, control box, and switch box. Inside, some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices are assembled into one The equipment of the power distribution device that meets the design function requirements. The high and low voltage distribution box is also called: high and low voltage switc...
