Horizontal vulcanized rubber sleeve cable and manufacturing process and device thereof

Abstract

The invention relates to a cable production method, discloses a horizontal vulcanized rubber sleeve cable and a manufacturing process as well as a manufacturing device thereof, and particularly relates to a horizontal vulcanized rubber sleeve cable of 35kv or above and a manufacturing process as well as a manufacturing device thereof. An insulation layer of the cable comprises the following materials in parts weight: 34-38 parts of CPE13513J, 4-6 parts of magnesium oxides, 8-12 parts of talcum powder, 0.8-1.2 parts of TA, 18-22 parts of light calcium carbonate, 0.8-1.2 parts of MT, 18-22 parts of kaolin, 0.7-0.9 part of silane, 0.1-0.22 part of RD, 0.1-0.22 part of A-150, 0.8-1.2 parts of paraffin waxes, 0.8-1.2 parts of ZD, 10-12 parts of dioctyl fat and 0.7-0.9 part of MM. The cable, process and device thereof disclosed by the invention have the beneficial effects that the cable is short in extrusion sizing time; silicone oil is taken as a medium, so that the cable has extremely small harmomegathus; the density of the silicone oil is close to that of the cable, so that the extension of the cable is stable, and a conductor is not eccentric, therefore, the cable is applicable to horizontal vulcanized pipelines; no building and no tower are used, thereby reducing the construction cost; no steam is used, related equipment is omitted, the energy consumption is low, and no emission are caused; the silicone oil is high in thermal efficiency, and the operating temperature is below 150 DEG C, so that no aging phenomenon is caused; and an effect of vulcanized crosslinking application is achieved, high-voltage cables above 35kv and extra-high-tension cables of 110-500kv are produced by using a horizontal production line, so that the production capability and level of cables are greatly enhanced.

Description

technical field [0001] The invention relates to a cable production method, that is, a flat sulfur rubber-sheathed cable and its manufacturing process and equipment, especially a 35kv and above high-voltage flat sulfur rubber-sheathed cable and its manufacturing process and equipment. Background technique [0002] Conductors are arranged in the existing rubber-sheathed cables, and the outside is coated with an insulating layer and a sheath. The insulating layer and the sheath are mostly made of natural styrene-butadiene, cis-butylene, chloroprene, EPDM, butadiene Made of other materials, the price is very high, ranging from 30,000 to 50,000 yuan per ton, and it is easy to age and has a short life, resulting in high cable prices. After the above materials are hot-melt extruded, they need to be vulcanized in steam at 170-220°C and 1.5-2.5Mpa, which requires boilers and other supporting equipment, high cost and energy consumption, and serious environmental pollution.

AI Technical Summary

Problems solved by technology

The insulating layer and the sheath are mostly made of natural styrene-butadiene, cis-butylene, chloroprene, EPDM, butadiene Made of other materials, the price is very high, ranging from 30,000 to 50,000 yuan per ton, and it is easy to age and has a short lifespan, resulting in high cable prices

After the above materials are hot-melt extruded, they need to be vulcanized in steam at 170-220°C and 1.5-2.5Mpa, which requires boilers and other supporting equipment. The cost and energy consumption are high, and the environmental pollution is serious.

In addition, the above-mentioned hot-melt materials cannot solidify quickly, and the cables cannot be run horizontally during the vulcanization process, otherwise the wires will be eccentric due to gravity, so the horizontal production line cannot be used, only the vertical production line can be used

Cables below 35Kv can use a 20-meter-high catenary production line, and cables above 110Kv must use a high-tower production line above 120 meters. The cost is as high as tens of millions or hundreds of millions of yuan, and the construction period is as long as two years. Limits the development of cable production
