Distribution box electrical consumer unit the mask is made of high quality flame retardant and high temperature resistant plastic cover.Separate special grounding wire screw reliable grounding more effective protection of the operator's safety,The box has high strength and is not easy to deform.The panel is made of insulating, environment-friendly, fire-resistant and self-extinguishing materials to reduce potential safety hazards.The surface of 0.8mm cold-rolled galvanized steel plate is electrostatic sprayed with powder, G solid and durable, high corrosion resistance.
Distribution box electrical consumer unit IP30 protection level, effectively prevent the entry of foreign matter, reduce dust accumulation.High purity zero line busbar, high conductivity, good electrical characteristics, lower heat in large current working state, safe and reliable.
The high temperature causes the service life of the electrical equipment of the Distribution Box Electrical Consumer Unit to be reduced.
The upper limit of the ambient temperature of electrical equipment designed and manufactured in accordance with the national standard should not exceed 40 ℃, and the operating distribution box exposed to the scorching sun in summer is due to the direct sunlight, the reflection of the heat from the cement floor and the equipment inside the box. The heat generated by itself sometimes exceeds 60°C in the box. Such a high temperature can easily cause the insulation of electrical coils and leads to breakdown and burn out; the electrical contacts increase contact resistance due to the high temperature, and the increase in contact resistance increases fever. Such a vicious cycle will eventually cause the contacts to burn out; at the same time; Too high temperature will also affect the stability of electrical protection functions, the reliability of actions, and the accuracy of measurement.
