Embodiment 1

[0013] As shown in Figure 1, the outer surface of the oxygen-free copper wire as the conductor 1 is extruded with a polyvinyl chloride (or polyethylene, cross-linked polyethylene) insulation layer 2 to form an insulated core, and two insulated cores are twisted into a pair. For the twisted wire group, the polyester tape wrapping layer 3 and the braided copper-clad aluminum or copper-clad aluminum alloy wire sub-shielding layer 4 are wound on the twisted wire group. The twisted pair with tape layer 3 and sub-shield layer 4 is used to form a cable, and at the same time, PP filling rope or non-alkali glass filling rope is used as filler 5, and polyester tape tape layer 6 is wrapped around it. Copper-clad aluminum or copper-clad aluminum alloy wire overall shielding layer 7 is braided on the belt layer 6, and an outer sheath 8 of polyvinyl chloride or halogen-free low-smoke flame-retardant polyolefin is extruded on the overall shielding layer 7.

Embodiment 2

[0015] As shown in Figure 2, the outer surface of the conductor 1 is made of oxygen-free copper wire, and the insulating layer 2 of polyvinyl chloride (or polyethylene, cross-linked polyethylene) is extruded to form an insulated core, and two insulated cores are twisted into a pair. For the twisted wire group, wrap the polyester tape wrapping layer 3 on the twisted wire group. The twisted pair with the tape layer 3 is used to form a cable, and at the same time, the filler 5 is filled with PP filling rope or alkali-free glass filling rope, and the polyester tape is wrapped around the tape layer 6 . Copper-clad aluminum or copper-clad aluminum alloy wire overall shielding layer 7 is braided on the belt layer 6, and an outer sheath 8 of polyvinyl chloride or halogen-free low-smoke flame-retardant polyolefin is extruded on the overall shielding layer 7.

Embodiment 3

[0017] As shown in Figure 3, the outer surface of the oxygen-free copper wire as the conductor 1 is extruded with a polyvinyl chloride (or polyethylene, cross-linked polyethylene) insulating layer 2 to form an insulated core, and multiple insulated cores are directly cabled. , and at the same time use PP filling rope or non-alkali glass filling rope as filler 5 to fill, and wrap polyester tape wrapping layer 6 around. Copper-clad aluminum or copper-clad aluminum alloy wire overall shielding layer 7 is braided on the belt layer 6, and an outer sheath 8 of polyvinyl chloride or halogen-free low-smoke flame-retardant polyolefin is extruded on the overall shielding layer 7.

Abstract

A new screen cable includes insulation coil cores on the conductor, a filling material, a belting layer, a screen layer and a sheathing characterizing that the screen layer is a wired layer of copper-clad aluminum or copper-clad aluminum alloy wires, the copper is uniformly distributed longitudinally on the outer surface of the aluminum or its alloy wires, both of them are concentric and are jointed by melt.

Description

technical field [0001] The invention relates to a cable structure, in particular to a widely applicable shielding structure of a power cable, a cable for electrical equipment and a communication cable, and belongs to the technical field of cables. Background technique [0002] Existing cables, for example, the wire-shielded cable whose patent application number is 03258099.1 is mainly composed of conductor, insulation, filler, polyester tape wrapping, shielding layer and outer sheath, etc., and its shielding layer is made of copper wire Spiral winding structure. Cable shielding can be divided into three forms: electrostatic shielding, static magnetic shielding and electromagnetic shielding. For shielded cables of low frequency systems, it mainly plays the role of electrostatic shielding. Electrostatic shielding is a grounded cavity conductor that can isolate the influence of internal and external electrostatic fields. In practice, metal meshes that are woven quite tightly a...
