Waterproof and anti-freezing suspension type rubber sleeve cable used for water pump

Abstract

The invention discloses a waterproof and anti-freezing suspension type rubber sleeve cable used for a water pump. The cable comprises a cable core; the cable core consists of a heat tracing band and three insulating wire cores which surround the periphery of the heat tracing band; the hollow position of the cable core is filled with thermal expansion ointment; a lead plastic or aluminum plastic composite longitudinally-wrapping layer is arranged outside the cable core; a semi-conductive water-blocking expansion band is arranged outside the lead plastic or aluminum plastic composite longitudinally-wrapping layer; a chloroprene rubber outer sheath is arranged outside the semi-conductive water-blocking expansion band; and the exterior of the chloroprene rubber outer sheath is coated with anti-freezing coating. The waterproof and anti-freezing suspension type rubber sleeve cable has the characteristics of ice and snow attachment prevention, anti-freezing property under water, and corrosion resistance, wearing resistance, aging resistance, surface self-cleaning, high physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, chemical reagent resistance and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a waterproof and antifreeze rubber-sheathed cable for a suspended water pump. Background technique [0002] With the rapid development of the wire and cable industry, the overall technical level of the industry has been greatly improved. The wire and cable industry is a basic industry. The Chinese government is actively stimulating domestic demand and increasing investment in the construction and renovation of urban and rural power grids. The development potential of domestic wire and cable is huge. Waterproof submersible cables are recognized by the industry as a type of cable product with relatively complicated technology. Common water pump connection cables generally use ordinary cables, but once the skin sheath of the connection cable is damaged, water will quickly penetrate into the cable and conduct electricity. The inner core is in direct contact with water to form a new c...

Problems solved by technology

Waterproof submersible cables are recognized by the industry as a type of cable product with relatively complicated technology. Common water pump connection cables generally use ordinary cables, but once the skin sheath of the connection cable is damaged, water will quickly penetrate into the cable and conduct electricity. The inner core is in direct contact with water to form a new conductive system, and part of the electric energy is conducted through the water, resulting in loss of electric energy and prone to safety accidents such as electric leakage

In addition, this cable works in water for a long time. In cold weather, the water is easy to freeze, and the cable is frozen and cannot work, which brings a lot of trouble
