Abstract

A waterproof intermediate alternating current cable is provided with a cable core body and an anti-aerugo PVC insulating layer wrapping the outer surface of the cable core body. And the anti-aerugo PVC insulating layer contains polyvinyl chloride with the polymerization degree of 1000-1300, diisononyl phthalate, epoxidized soybean oil, polyethylene wax and an anti-aerugo compatilizer. The anti-aerugo PVC insulating layer is further provided with a waterproof layer and an outer sheath layer, the waterproof layer wraps the outer surface of the cable core body, and the outer sheath layer wraps the outer surface of the waterproof layer. The anti-aerugo PVC insulating layer of the waterproof intermediate alternating current cable contains the anti-aerugo compatilizer, so that the conductor surface of the cable core body can be prevented from being oxidized, the blackening phenomenon is avoided, the problems of safety and long service life of a cable product are solved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a waterproof medium-crossing cable. Background technique [0002] A cable is a rope-like cable that is usually twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Has a highly insulating covering. Cables have the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, and aluminum alloy cables. And so on, they are all composed of single-strand or multi-strand wires and insulation layers, used to connect circuits, electrical appliances, etc. At present, for cables used in household installations and surrounding humid environments, copper cable conductors ...
