Description

Technical Field

[0001] The utility model relates to the technical field of electric wire protection, in particular to an electric wire protection structure. Background Art

[0002] Food processing plants require a large number of workers when processing food, and the workers are usually arranged to live in dormitory buildings. In order to improve the living safety of workers, the engineering department needs to regularly inspect the wires in the dormitory buildings. When the wires are installed and used in the dormitory buildings, a concrete hole is often dug on the balcony for the power lines to pass through, and then the exposed wires are protected by installing wire troughs. However, long-term exposure of the wire troughs to the air will cause the wire troughs to rust and corrode, causing the wire troughs to be damaged, and rainwater will enter the inside of the wire troughs. After that, the rainwater will flow along the gap between the concrete hole and the wires to the lower floors, affecting human activities on the lower floors. In addition, the wires are prone to friction with the concrete in the concrete hole, causing the insulation of the wires to be damaged, and then leakage occurs. Utility Model Content

[0003] The purpose of the utility model is to design a wire protection structure so as to solve the problems mentioned in the background technology.

[0006] Furthermore, a sealant is coated on the gap between the outer wall of the flame retardant layer and the top of the foamed rubber layer.

[0007] Furthermore, the outer periphery of the sealant is wrapped with a water stop ring.

[0008] Furthermore, an anti-corrosion layer is wrapped between the electric wire and the waterproof layer.

[0009] Furthermore, the anti-corrosion layer is an asphalt coating.

[0010] Furthermore, the protective sleeve is a PVC-U sleeve.

[0011] Furthermore, the waterproof layer is a polyvinyl chloride layer.

[0012] Furthermore, the flame retardant layer is a composite mica tape.

[0013] The beneficial effects of the utility model are:

[0014] By setting the protective cover, the insulation sheath of the wire can be effectively protected to prevent the wire from rubbing against the concrete in the concrete hole and causing the insulation sheath of the wire to be damaged;

[0015] By setting a foam layer to seal the gap between the concrete hole and the wire, when the wire trough is damaged, rainwater cannot flow along the gap between the concrete hole and the wire to the lower floors, thus avoiding affecting human activities on the lower floors.

[0016] By providing a waterproof layer, the waterproof performance of the wire can be improved, so that the wire can be used safely when immersed in water. By providing a flame retardant layer, the high temperature resistance and flame retardant performance of the wire can be improved, making the wire safer to use in a high temperature environment.
