Fireproof cable tray is provided with good heat insulation, fire resistance, corrosion resistance and is suitable for the performance of a wide range of environments, also has the advantages of light weight, big bearing capacity, safe and reliable, technically reached the domestic advanced level. Our fire bridge with steel casing, double fire cover filled with inorganic fireproof slot box structure, good strut internal structure, inorganic fireproof slot box can be effectively fixed, the average thickness of the insulation layer 25mm. Ventilation and heat radiation of the double deck cover plate, the inner spraying fire retardant coating, the coating expansion in case of fire, blocking the heat radiation hole, and protecting the cable in the box. Fire resistance performance of inorganic fireproof trough box through the 60 minute fire resistance test of national fixed fire resistance test center.

For different use occasions, the fire tank can be divided into four parts:

1, refractory fully enclosed tank box: This product is suitable for 10KV following power cable, and control cable, lighting wiring and other indoor and outdoor overhead cable trench, tunnel laying.

2, fire-resistant type semi closed groove box: the product can withstand flame BBQ, tank temperature can be limited to allow the value of the safe operation of cables, the box cover for the double cover. In addition to water-resistant features, in the case of high temperature can be automatically whereabouts cover cooling air holes.

3, cable tunnel with refractory box: the product can be widely used in tunnel, underground public facilities, etc.. Have good ventilation, when the tank caught fire or cable box overheating, due to fire the original open the impregnated with a special fireproof coating of ventilation network congestion and expansion into thick carbon fines clad cable, online automatic small cap the whereabouts, surface covered network, self extinguishing burning hypoxic medium.

4, refractory type inorganic groove box: the product with inorganic materials and glass fiber reinforced constitute, structure fireproof fully closed, effectively prevent the harm of cable combustion and external fire, on the other because of the use of inorganic materials, especially for to serious corrosion of acid and alkali environment.
