The development trend of Waterproof Case

With the development of Waterproof Case, with the requirements of urban power and communication construction requirements for wires and cables, communication cables and signal cables to be buried, solutions for cable branching, connection, and waterproofing are very important proposals. Plastic Waterproof Case has been successfully used abroad for more than 20 years, and it is also widely used in my country. Before 2000, most of the metal waterproof cases made of iron were used in our country; after 2000, my country's science and technology developed rapidly, and the plastic technology was gradually improved. The plastic gradually replaced the metal waterproof case with its low cost, good insulation and high degree of waterproofness.
