Problems solved by technology

[0003] At present, the repair of cables usually adopts the method of pressure-sensitive repair tape and vulcanization heat repair method. Among them, the pressure-sensitive tape is easy to operate and is widely used in power engineering. However, this method also has inherent technical defects, such as: Low strength and easy aging; due to the short actual repair length of the cable, the requirements for the heat dissipation performance of the tape are relatively low, but the requirements for its heat insulation and heat resistance performance are high, and need to be further improved; the tape's The insulation performance is relatively poor, and although the insulation performance is improved by multi-layer winding, the he

Abstract

The invention discloses a cable protective belt and a manufacturing method thereof. The cable protective belt sequentially comprises an insulating layer, an elastic rubber pad layer, a reinforcing layer, an inner protective layer and an outer protective layer from bottom to top. The lower surface of the insulating layer is coated with glue solution, the elastic rubber pad layer is attached to the upper surface of the insulating layer through glue solution in an adhesive mode, the reinforcing layer is disposed on the upper surface of the rubber pad layer and comprises a copper wire mesh belt and copper fibers, the inner protective layer is arranged on the upper surface of the reinforcing layer and internally provided with evenly distributed cavities, the outer protective layer is attached to the outer surface of the inner protective layer through glue solution in an adhesive mode, and the glue solution is adhesive for rubber. The cable protective belt and the manufacturing method have the advantages that the structure is composed of multiple layers, fineness of the structure and close fit are achieved, construction operation is easy, construction normalization is improved, and meanwhile heat resistance and heat insulation performance of materials are improved on the basis that common repair mode performance is satisfied.

Description

technical field [0001] The invention relates to a material for repairing or protecting cables and a manufacturing method thereof, in particular to a cable protective tape and a manufacturing method thereof. Background technique [0002] It is an important measure to ensure the safe operation of power cables and prevent cable failures by regularly performing maintenance inspections on power cables, early detection of hidden dangers in the operation of power cables, and cable repair and maintenance. Due to the influence of various factors such as operating environment, carrying voltage and construction conditions, the fault frequency of power cables occurs frequently. [0003] At present, the repair of cables usually adopts the method of pressure-sensitive repair tape and vulcanization heat repair method. Among them, the pressure-sensitive tape is easy to operate and is widely used in power engineering. However, this method also has inherent technical defects, such as: Low st...
