Material composition of Encyclopedia of electricity meter box

The material used to manufacture the low-voltage cable branch box is a resin matrix composite material. The main components of the box are injection molded and pressed from ABS engineering plastics, polycarbonate transparent PC materials, DMC and SMC. The composite consists of two parts: matrix polyester resin; Reinforcing material (hereinafter referred to as PC and SMC), so it is also called transparent PC material and fiber-reinforced polyester material. Transparent PC material and fiber-reinforced unsaturated polyester are composite materials based on unsaturated polyester resin. These two materials are insoluble, flame retardant and recyclable. The latter material has the disadvantages of non melting and non recyclable. Its physical structure is three-dimensional network structure This material has become a high-performance engineering material through the modification of functional fillers and the reinforcement of special fibers. In Europe and the United States and other developed countries, this material has been widely used in the electrical field as early as decades ago.

Compared with the past, today's meter box has greatly improved in function, performance and energy saving.
