Problems solved by technology

[0002] At present, there are many kinds of semi-conductive braid products used in high-voltage cable occasions, and each has its own characteristics, but there is still no semi-conductive braid with all kinds of performance, and some surface resistance and volume resistance are too large , some have poor water blocking performance, insufficient expansion height and expansion speed, and some have poor tensile strength, but there has not been a copper wire braided semiconductive resistance water shielding tape with flame retardant properties, which makes its application range subject to certain restrictions

Embodiment Construction

[0023] The present invention includes a base cloth and conductive liquid and flame retardant liquid attached to the base cloth. The base cloth is woven from warp 1 and weft 2. Warp 1: each unit consists of a 30-45 double-strand non-alkali glass fiber The yarn and a φ0.2mm tinned copper wire are arranged in parallel, and the weft yarn 2: 30-45 single-strand glass fiber yarns.

[0024] The preferred method of the present invention: warp yarn 1: each unit is composed of a 45 double-ply non-alkali glass fiber yarn and a φ0.2mm tinned copper wire, and weft yarn 2: 30 single-ply glass fiber yarn.

[0025] The present invention carries out according to the following processing steps:

[0026] 1) Material selection: warp yarn 1: each unit is composed of a 30-45 double-strand non-alkali glass fiber yarn and a φ0.2mm tinned copper wire arranged in parallel, weft yarn 2: 30-45 single-strand glass fiber yarn;

[0027] 2) Weaving, sending warp yarn 1 and weft yarn 2 to a high-speed knitt...

Abstract

The invention discloses a water-repellent semiconducting metal-shielded flame-retardant braided strap. The water-repellent semiconducting metal-shielded flame-retardant braided strap comprises a base fabric, and conductive liquid, flame-retardant liquid and a water-repellent adhesive attached to the base fabric; and the base fabric is formed by braiding wraps and wefts. The processing technology comprises the following technological steps of: 1) sorting: sorting the wraps and the wefts; 2) braiding: braiding the wraps and wefts by using a high-speed braiding machine; 3) coating the conductive liquid: coating the conductive liquid on the base fabric in a liquid-immersing groove; 4) drying: drying the base fabric, rolling and leveling; 5) coating the flame-retardant liquid: coating the flame-retardant liquid on the treated base fabric in the liquid-immersing groove; 6) drying: drying the base fabric, rolling and leveling; and 7) packaging: performing vacuum packaging on the braided strap to form a finished product. The water-repellent semiconducting metal-shielded flame-retardant braided strap has the advantages of semiconduction, water-repellent and flame-retardant property, high heat resistance grade, high tensile strength, and energy conservation, consumption reduction and environmental protection in the production process.

Description

technical field [0001] The present invention relates to a semi-conductive braid, in particular to a semi-conductive braid suitable for high-voltage occasions such as ultra-high-voltage power cables, high-voltage mining cables, and high-voltage marine cables, and its processing technology. Background technique [0002] At present, there are many kinds of semi-conductive braid products used in high-voltage cable occasions, and each has its own characteristics, but there is still no semi-conductive braid with all kinds of performance, and some surface resistance and volume resistance are too large , some have poor water blocking performance, insufficient expansion height and expansion speed, and some have poor tensile strength, but there has not been a copper wire braided semiconductive resistance water shielding tape with flame retardant properties, which makes its application range Subject to certain restrictions. Contents of the invention [0003] In view of the above def...
