Embodiment Construction

[0013] The present invention will be described in further detail below.

[0014] A twisted wire cable with a reinforced layer, which uses a conductor as an inner conductor; a copper layer is arranged on the inner conductor; a reinforced layer is arranged outside the copper layer; an insulating layer is arranged outside the reinforced layer; and a cable sheath is arranged outside the insulating layer .

[0015] Preferably, the conductive core is formed by twisting a plurality of monofilaments.

[0016] Preferably, the monofilament has a semicircular cross section.

[0017] Preferably, the number of monofilaments is even.

[0018] Preferably, the structure of the conductive core is formed by arranging two monofilaments opposite each other to form a circle, and then twisting a plurality of double monofilaments that have been synthesized into a circle.

[0019] The stranded wire cable with the reinforcement layer of the present invention has a reasonable structural ratio and si...

Abstract

The invention discloses a stranded cable with a reinforcing layer. A conductive body is used as an inner conductor. A copper layer is arranged on the inner conductor. A reinforcing layer is arranged outside the copper layer. An insulating layer is arranged outside the reinforcing layer. A cable sheath is arranged outside the insulating layer. The conductive core is stranded from a plurality of monofilaments. The cross sections of the monofilaments are semicircular. The number of the monofilaments is even. The structure of the conductive core is that every two monofilaments are arranged oppositely into a circle and then multiple double monofilaments combined into a circle are stranded. The stranded cable with a reinforcing layer of the invention has the advantages of reasonable structure proportion and simple technology. The reinforcing layer is arranged in the insulating layer, which can enhance the strength of the cable.

Description

technical field [0001] The invention relates to the field of cable processing, in particular to a stranded cable with a reinforcing layer. Background technique [0002] With the development of the economy and the consumption of natural resources, the power cable is an important part of the power transmission system, which usually includes a conductive core and an insulating layer wrapped around the core. The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. [0003] The continuous and rapid growth of China's economy has pro...
