CN104282363A - High-strength mobile type cable - Google Patents

Abstract

The invention relates to a cable, in particular to a high-strength mobile type cable. The high-strength mobile type cable is composed of a thermoplastic rubber sheath and four inner cores; each inner core is composed of a copper conductor and a thermoplastic rubber insulating layer, and each copper conductor is located in the corresponding thermoplastic rubber insulating layer. The high-strength mobile type cable has the rubber elasticity, is resistant to aging and lower temperature, retards inflaming, and has the mechanical performance of common thermoplastic PVC.

Description

High strength movable cable

Technical field:

The present invention relates to a kind of cable, more particularly, relate to a kind of high strength movable cable.

Background technology:

Traditional heavy General rubber sleeve cable, production process more complicated, cost of manufacture input property is larger, in butylbenzene mixture rubber production process, conductor must adopt tinned conductor or wrapped one deck polyester belt outside conductor, in use prevent the sulphur compound chemically reactive in copper and quality of rubber materials, copper conductor is caused to be oxidized its electric conductivity and reduction in useful life, and the more difficult control of technique in production process, sulfuration program is had to pass through in butylbenzene mixture rubber extrusion, the more difficult control of state of cure (vulcanization), if grasp the easy adhesion of bad core or sulfuration incomplete, produce post-cure.

Summary of the invention:

The present invention is exactly for the problems referred to above, provides a kind of high strength movable cable.

To achieve these goals, the present invention adopts following technical scheme,

Be made up of thermoplastic elastomer sheath and four inner cores, inner core is made up of copper conductor and thermoplastic elastomer insulating barrier, and copper conductor is positioned at thermoplastic elastomer insulating barrier;

Described thermoplastic elastomer sheath is made up of modified PVC elastomer or TPU material;

Described thermoplastic elastomer insulating barrier is made up of modified PVC elastomer or TPU material;

Described copper conductor is non-zinc-plated six class annealed copper strand wires or the zinc-plated annealed copper strand wire of six classes.

Described inner core inscribe and outside thermoplastic elastomer sheath; Adjacent inner core is mutually circumscribed.Beneficial effect of the present invention:

1, the present invention has caoutchouc elasticity, ageing-resistant, low temperature resistant, fire-retardant, possesses again the mechanical performance of common thermoplastic PVC (polyvinyl chloride).

2, the present invention is without the need to sulfidation, and production process is more easy to control, and without the need to any band and auxiliary material, sheath is low temperature resistant, ageing-resistant thermoplastic elastomer material, without the need to sulfuration in extrusion, simple to operate, stable performance.Solving existing product greatly becomes conductor in product process must adopt tinned conductor or wrapped one deck polyester belt outside conductor at butylbenzene mixture rubber, sulphur compound chemically reactive in use in copper and quality of rubber materials, copper conductor is caused to be oxidized its electric conductivity and reduction in useful life, and more difficult control in production technology; have to pass through sulfuration program in butylbenzene mixture rubber extrusion; the more difficult control of state of cure (vulcanization); if grasp bad; the easy adhesion of core or sulfuration incomplete; produce post-cure, the problem such as cause product defective.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present invention.

In Fig. 1,1 is thermoplastic elastomer sheath, and 2 is inner core, and 3 is thermoplastic elastomer insulating barrier, and 4 is copper conductor.
