Waterproof soft cable

Abstract

The invention discloses a waterproof soft cable which comprises a cable core. The cable core is formed by twisting three insulating wire cores. A stuffing layer formed by stuffing is arranged in a gap in the cable core. The outmost layer of the cable is coated with a polyurethane elastomer outer protective layer in an extruding mode. Each insulating wire core is composed of a copper conductor and insulating layers sequentially wound on outside the conductor. Compared with an existing waterproof cable, fundamental difference is that an outer protective sleeve is made of a different material, and therefore the waterproof soft cable has the functions of an ordinary waterproof cable, can work normally under the extremely cold condition of low temperature of -40 DEG C and is pressure resistant, anti-abrasion, anti-corrosion and capable of maintaining soft performance.

Description

[0001] technical field [0002] The invention relates to the field of wires and cables, in particular to a low-temperature-resistant, pressure-resistant, corrosion-resistant, waterproof flexible cable. Background technique [0003] Since the beginning of the 21st century, with the continuous development of electric power industry, data communication, automobile industry and transportation industry, the demand and requirements for wire and cable have also increased rapidly, which makes the future cable industry have huge development potential. [0004] At present, the existing cables are mainly composed of inner conductors, insulating layers, outer conductors and sheaths; due to their use requirements, they are more exposed to the outdoors, and outdoor construction often encounters such as low-temperature cold currents, acid-base corrosion, oil pollution, crowding, etc. When the sheath is damaged or the joints at both ends of the cable are not tightly sealed, moisture and rai...

Problems solved by technology

[0004] At present, the existing cables are mainly composed of inner conductors, insulating layers, outer conductors and sheaths; due to their use requirements, they are more exposed to the outdoors, and outdoor construction often encounters such as low-temperature cold currents, acid-base corrosion, oil pollution, crowding, etc. When the sheath is damaged or the joints at both ends of the cable are not tightly sealed, moisture and rainwater can easily infiltrate along the braided outer conductor and corrode the outer conductor, thereby reducing the shielding performance of the outer conductor. , causing the attenuation constant to increase, the shielding attenuation to decrease, and the insulation resistance to decrease, etc. When the outer conductor of the cable is severely corroded, the cable will be scrapped due to loss of transmission function

It may even cause water droplets to seep into the connectors and cabinets, resulting in serious consequences of damaging the entire cabinet equipment
