Problems solved by technology
If it cannot be effectively removed, these cross-linked by-products will remain in the insulation in the form of micropores, which will bring safety hazards to power transmission, and serious accidents such as explosions will occur
There is a way to remove the cross-linked by-products by placing the cable reel in a sealed degassing chamber. Since the cross-linked cables are wound on the cable reel layer by layer, the cables in the inner layer of the reel cannot be degassed. Therefore, Poor degassing effect

The invention relates to an inspiratory wire coil. The inspiratory wire coil comprises a cylinder body, a seamless steel tube, support channel steel, outside plates and a corrugated plate, wherein the outside plates are fixed at the two ends of the cylinder body in a welding manner; the outer end of the support channel steel is welded on the cylinder body; inspiratory ports are formed in the outside plates at the two ends of the cylinder body; and a plurality of inspiratory long grooves are formed inside the cylinder body, and are fixed on the support channel steel. The inspiratory wire coil has the advantages of novel structure and easiness in manufacturing, has a good removal effect of methane and other by-products in a cable, and can exhaust waste gas to ensure the safety and long-term effect of the cable during use.
Description
technical field [0001] The invention relates to a special equipment for removing insulation by-products produced in the manufacturing process of high-voltage and ultra-high-voltage cross-linked cables, in particular to a suction coil. Background technique [0002] The cross-linking method of the insulation of high-voltage and ultra-high-voltage cross-linked cables is peroxide cross-linking. Polyethylene is used as the base material, and 1.5%~2% of dicumyl peroxide (DCP) is added as a cross-linking initiator. , there will be four by-products in the crosslinking process: water, methane, styrene and acetophenone, the concentration is about 200ppm. If it cannot be effectively removed, these cross-linked by-products will remain in the insulation in the form of micropores, which will bring safety hazards to power transmission, and serious accidents such as explosions will occur. There is a way to remove the cross-linked by-products by placing the cable reel in a sealed degassing ...
