This product is specifically designed for the protection and maintenance of cable trenches. It is made through a one-step high-temperature and high-pressure molding process using composite resin, glass fiber, and steel reinforcement framework. It combines high strength with light weight – meeting the load-bearing requirements (suitable for pedestrian and light vehicle passage scenarios), with a weight only 1/3 of traditional cast iron covers. A single person can easily transport and install it, significantly reducing construction and maintenance costs. Key advantages are prominent: The non-metallic material has excellent insulation properties, effectively avoiding the risk of electric shock, and is suitable for use in power and communication cable trenches; resistant to acid and alkali, corrosion-resistant, able to withstand long-term dampness and chemical environments without rusting or aging, with a service life of up to 15-20 years; has no recycling value, fundamentally eliminating the problem of theft and ensuring the safety of cable facilities; the surface has a non-slip texture design, making it easy to walk without slipping, the cover seat fits tightly, and there is no noise when passing. The product size specifications can be customized as needed. The edges are sealed to fit tightly, effectively preventing dust, water, and debris from falling into the cable trench, protecting the internal cables. It is widely used in cable trenches and troughs of substations, distribution rooms, municipal roads, residential areas, industrial parks, communication base stations, etc., as a safe and environmentally friendly alternative to cast iron and cement covers.
