Abstract

The utility model discloses a silicone rubber control cable. The cable comprises multiple copper conductors which are wrapped in an inner wrapping layer, wherein in the inner wrapping layer, each copper conductor is wrapped in a silicone rubber insulation layer, and a reinforced steel wire rope formed by intertwisting and bundling steel wires is arranged between two adjacent silicone rubber insulation layers. The inner wrapping layer is successively wrapped in a tin-coated copper wire braided shielding layer and a silicone rubber sheath layer, wherein a filling layer formed by high-temperature-resistant magnesia power is additionally arranged between the tin-coated copper wire braided shielding layer and the silicone rubber sheath layer. According to the utility model, silicone rubber with good flexibility is employed, and the reinforced steel wire ropes are arranged, so that mechanical strength of the cable is improved and service life of the same is prolonged.

Description

The silicon rubber control cable

Technical field:

The utility model relates to cable, mainly is a kind of silicon rubber control cable.

Background technology:

Control cable is applicable between the transmission line of making electrical equipment, instrument, automatic control system in the industries such as oil, chemical industry, electric power, metallurgy and the mobile electric equipment or the laying of fixture, it requires high temperature resistant pliability good, but the existing control cable of using is flexible good, toughness is just relatively poor relatively, perhaps just influence is flexible for good-toughness, and flexible and toughness can not both have concurrently.

The utility model content:

Technical problem to be solved in the utility model provides a kind of silicon rubber control cable, and it adopts the good silica gel of softness, and is provided with the mechanical strength that the reinforcement steel wire rope has improved cable simultaneously, carries and having done useful life.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of silicon rubber control cable, include many copper conductors, it is characterized in that: described many copper conductors are coated with lapping layer in one deck, the inherent every copper conductor of lapping layer is coated with one deck silicone rubber insulation layer outward respectively in described, be provided with the reinforcement steel wire rope by the stranded bunchy of steel wire between the silicone rubber insulation layer in described outside the inherent adjacent copper conductor of lapping layer, described lapping layer is coated with the screen and the silicone rubber jacket layer of tinned copper wire braiding outward successively.

Have additional the packed layer that constitutes by the high temperature oxidation resisting magnesium dust between the screen of described tinned copper wire braiding and the silicone rubber jacket layer.

The utility model has the advantages that:

The utility model adopts the good silica gel of softness, and is provided with the mechanical strength that the reinforcement steel wire rope has improved cable simultaneously, carries and having done useful life.
