Abstract

The invention discloses a control cable of a flat structure. The control cable comprises a plurality of wires. An inner butyronitrile rubber insulating layer and an outer butyronitrile rubber insulating layer wrap the wires. A reinforcing layer formed by weaving nylon fiber is arranged between the inner butyronitrile rubber insulating layer and the outer butyronitrile rubber insulating layer. An isolating layer formed by overlapping and wrapping high-flame-retardant fiber bands wraps the inner butyronitrile rubber insulating layer and the outer butyronitrile rubber insulating layer. Rubber frameworks are arranged on the portions, between the wires and the insolating layer, in the isolating layer formed by overlapping and wrapping the high-flame-retardant fiber bands. A zinc-coated steel wire knitted armor layer, a metal shielding layer and a flame-retardant external protective sleeve layer sequentially wrap the isolating layer which is formed by overlapping and wrapping the high-flame-retardant fiber bands. A reinforcing insulating layer is arranged between the metal shielding layer and the flame-retardant external protective sleeve layer. According to the control cable, the insulating layers high in insulation performance are designed, the isolating layer is also arranged, and therefore insulation performance and isolation performance are good, and practicability is high.

Description

Technical field [0001] The invention involves a type of control cable, mainly a flat -shaped structure control cable. Background technique [0002] Control cables are suitable for transmission cables for electrical, instruments, and automatic control systems in industries such as electricity. They focus on the security of signal transmission. Therefore, it is required to have good insulation performance and ensure the mechanical strength of the cable at the same time.The current insulation and cover materials used in the cables are poor and brittle cracking, which affects the performance of the cable. Invention content [0003] The technical problem to be solved by the present invention is to provide a flat -shaped structure control cable. Its design has a multi -layer insulation performance of the insulatability layer, and it also has an isolation layer. Therefore, the insulation isolation performance is good and the practical performance is strong.The insulating layer used in ...
