Box-type substation

Box-type substation

A new type of environmental protection material is adopted for the box, namely, unsaturated polyester glass fiber reinforcement membrane material (SMC), which can withstand the impact of various environmental and climatic conditions and chemical erosion and has the service life of more than 30 years. The modular combination and high-performance sealing design are adopted for the box. The entire box has a higher sealing performance, and can effectively prevent rain, dust and insect pests, in which the protection performance can reach the requirement of IP54 in GB4208. The box is designed with the unique internal and external air exchange channel, and meanwhile it can be equipped with ventilation fan (optional) to timely regulate the temperature and humidity in the box and has the functions of being waterproof, vapor-proof and adjustable to steam high and low temperature environment, etc. The three-point lock of ring network cabinet with waterproof cover is adopted for the box, and meanwhile it is equipped with a special metering lock (optional) which is safe and reliable and can meet the different requirements of customers.
