Abstract

The utility model relates to a cable for computers and meters, which is characterized by comprising seven conductor groups in a "1*6" arrangement inside the cable. Each conductor group is composed of two internally inter-twisted cable conductors (1), wherein the outside of each cable conductor (1) is wrapped with a polyethylene insulating layer (2). The outside of the two inter-twisted cable conductors (1) is wrapped with a shielding layer (3) and the inner side of the shielding layer (3) is provided with a drainage wire (4). The outside of the shielding layer (3) is wrapped with a polyester film wrapping layer (5). From inside to outside, the outside of the seven conductor groups is sequentially coated with a first wrapping layer (6), a second wrapping layer (7), a third wrapping layer (8), a polyvinyl chloride inner sheath (9), a steel belt armor layer (10) and a polyvinyl chloride outer sheath (11). According to the technical scheme of the utility model, the cable for computers and meters has the advantages of high flame-retardant performance and high shielding performance.

Description

Computer and instrument cable

Technical field

The utility model relates to a kind of computer and instrument cable, belongs to field of cables.

Background technology

The application of electronic computer, instrument and meter is day by day universal, and people's awareness of safety constantly strengthens, and the performance of the cable supporting with it and environmental requirement are also improved constantly.Existing computer and instrument are high temperature resistant not high with fire resistance with cable, and under fire condition, the security reliability of cable is low, and shielding properties and interference free performance are not high, are not suitable for use in densely populated and higher to device security reliability requirement place.Therefore seek a kind of computer and instrument with high flame resistance, high shielding properties particularly important with cable.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of computer and instrument cable with high flame resistance, high shielding properties is provided.

The purpose of this utility model is achieved in that

A kind of computer and instrument cable, it comprises seven conductor groups that inner 1*6 arranges, described conductor group comprises inner two stranded cable conductors mutually, described cable conductor outside is coated with polyethylene layer, two cable conductor outsides after stranded are enclosed with screen, described screen is copper strips or aluminum plastic belt screen, the inner side of described screen is provided with drainage thread, the outside of described screen is also enclosed with polyester film lapping layer, seven conductor group outsides are enclosed with the first lapping layer from the inside to the outside successively, the second lapping layer, the 3rd lapping layer, polyvinyl chloride inner sheath, steel-tape armouring layer and polyvinyl chloride oversheath.

Compared with prior art, the beneficial effects of the utility model are:

The utility model computer and instrument have advantages of high flame resistance, high shielding properties with cable, can transmit reliably faint analog signal, can be widely used in detection and control computer system or the automation equipment of the departments such as generating, metallurgy, oil, chemical industry, light textile, and on general industrial computer.
