New composite outdoor distribution box

outdoor distribution box is used for power distribution and control of power, lighting and distribution equipment. It is suitable for all kinds of harsh environments and outdoor public places such as substations, industrial and mining enterprises, urban roads, residential quarters, high-rise buildings, airports, etc. At present, the metal distribution box widely used in the power system has the following problems: (1) its own conductivity, there are potential safety hazards; (2) Poor corrosion resistance and short service life; (3) The box is seriously stolen, threatening public safety and increasing the use cost; 4) The corrosion is serious, and the coating is easy to peel off, which seriously affects the beauty of the environment

smc distribution box product components are made of glass fiber reinforced unsaturated polyester resin (SMC) through high-temperature molding and building block lapping. The modular plate structure can be easily assembled with the simplest tools. The environmental protection box without halogen, phosphorus and other harmful substances is greatly superior to the traditional metal box in the trial environment, safety, service life, processing and installation. SMC composite material is also called sheet mold, but there is also a kind of equipment for cement pipe. The ring stiffness tester is mainly used for testing other mechanical properties. Plastic materials (sheet molding compounds, SMC) are unsaturated polyester glass fiber composites made of unsaturated polyester resin as adhesive, adding glass fiber, filler, pigment and other additives, impregnating glass fiber yarn, and covering both sides with film. Using this material, products with different shapes can be made by molding process. Because of its good formability and aging resistance, it is widely used in automotive industry, railway vehicles, construction projects to ensure that belts never deviate, as well as electrical industry and communication engineering. The box, which is simply assembled from SMC plate products, is used in the power equipment manufacturing industry to replace the metal distribution equipment box widely used in the current power industry, and has the following significant advantages

(1) insulating material, high safety factor. SMC has excellent electrical insulation performance, high insulation resistance and high power frequency dielectric strength

(2) high and low temperature resistance, aging resistance, beauty and environmental protection. SMC maintains good mechanical properties in a wide temperature range; It is resistant to sunlight and ultraviolet rays, and has good aging resistance; It is a beautiful, environmentally friendly and energy-saving material

(3) flame retardant, low smoke, anti-corrosion and anti-theft. The flammability grade of SMC material is fv0, which belongs to flame retardant material; It has good corrosion resistance, can resist the corrosion of dilute acid, alkali and salt, and has good resistance to a variety of organic solvents and seawater; It is useless to synthesize metal materials that do not measure the cross-sectional diameter at both ends and the middle of the test piece

(4) thermal insulation material, with good thermal insulation effect. SMC is a kind of thermal insulation material, which can delay the impact of external ambient temperature changes on the internal temperature of the box, and the market recovery range reaches 10.1 billion yuan

(5) small specific gravity and excellent mechanical properties. The specific gravity of glass fiber reinforced polyester material is between 1.7 ~ 2.0, and the weight is light; It has high tensile strength, bending strength and impact strength

(6) no electromagnetic shielding. SMC is a non-metallic material, which has no electromagnetic shielding effect, does not reflect and block the propagation of microwave, facilitates wireless communication, and can be used for remote measurement and monitoring
