Problems solved by technology
However, from the perspective of use, most silicone rubber flat cables have radial core breakage and surface fracture after less than three years of use, resulting in the scrapping of the entire cable, greatly shortening the product life, and causing great losses to users.

Abstract
A leakage-proof flat cable for a deep-well pump disclosed by the present invention comprises core conductors 1, core conductors 2, insulated wire cores and a sheath, the core conductors 1 and the core conductors 2 are arranged in parallel, a plurality of groups of core conductors 1 are arranged at equal intervals, the insulated wire cores are respectively extruded on the outer sides of the core conductors 1 and the core conductors 2, and the sheath is arranged on the outer side of the insulated wire cores. The insulating wire cores form isolating layers outside each group of core conductors I and core conductors II, the isolating layers are not adhered to each other, and the sheath is extruded outside the insulating wire cores and is filled in gaps of the insulating wire cores. The invention belongs to the technical field of wire and cable manufacturing, and particularly relates to a leakage-proof flat cable for a deep-well pump, which is good in anti-seepage performance, high in resistance and stable in cold resistance.
Description
technical field [0001] The invention belongs to the technical field of wire and cable manufacturing, in particular to a leak-proof flat cable for deep well pumps. Background technique [0002] Due to the particularity of the deep well pump, the power cord must have high insulation resistance and good sealing to prevent the oil leakage in the pump caused by the pressure generated during the operation of the pump motor and cause the motor to burn out. This kind of power cord is imported for a long time. This kind of cable can reduce dependence on imports. [0003] Silicone rubber itself has the characteristics of high temperature resistance, cold resistance, softness and corrosion resistance, so the cable has stable electrical performance in high temperature environment, good anti-aging performance and long service life. It is suitable for AC 1kV and below with special requirements such as heat resistance, cold resistance and corrosion resistance. Power transmission lines and...
