Problems solved by technology
[0003] When the cable works in a cold environment, due to the influence of low temperature, the cable insulation layer on the surface will harden and break easily, so that the working life of the cable is lower than that of the cable working at normal temperature, and the risk of electric leakage is prone to occur
[0004] Due to structural reasons, cable trays with the same specifications on the market can only be adapted to cables of the same size and diameter. When supporting cables with different diameters, it is necessary to purchase cable trays with different specifications, resulting in high cable support costs. The phenomenon

The invention relates to the technical field of cable bridges, in particular to a cable bridge used in a low-temperature environment, which comprises a rack, six fixing screws are fixedly arranged on the left side and the right side of the upper end face of the rack, an internal working cavity is formed in the rack, an internal clamping box is fixedly arranged on the upper wall of the internal working cavity, and a heating clamping cavity is formed in the internal clamping box. According to the invention, constant-temperature heating can be carried out through air entering the bridge, so that a cable can work in a constant-temperature environment for a long time, the service life of the cable is prolonged, the phenomenon of hardening and fracture of an insulating layer is avoided, and the service life of the cable is prolonged. According to the cable bridge, clamping with different diameter requirements can be realized under the action of the clamping exhaust roller and the spring, so that the cable bridge can clamp cables with different calibers at the same time, and the cable clamping working cost is further reduced.
Description
technical field [0001] The invention relates to the technical field of cable trays, in particular to a cable tray used in a low temperature environment. Background technique [0002] Cable tray is a rigid device that supports cables in work, and is widely used in cable transmission work. [0003] When the cable works in a cold environment, due to the influence of low temperature, the cable insulation layer on the surface will be hardened and easily broken, so that the working life of the cable is lower than that of the cable working at room temperature, and the risk of leakage is prone to occur. [0004] Due to structural reasons, cable trays with the same specifications on the market can often only be adapted to cables of the same size and diameter. When supporting cables with different diameters, it is necessary to purchase cable trays with different specifications, resulting in high cable support costs. The phenomenon. SUMMARY OF THE INVENTION [0005] The purpose of ...
