Submarine cable tray degassing chamber

Abstract

The invention discloses a submarine cable tray degassing chamber. The submarine cable tray degassing chamber comprises a rotary disc chassis base; a rotary disc is arranged below the rotary disc chassis base; a side guide rail is arranged on the outer side of the rotary disc; a driving motor is arranged below the rotary disc chassis base; the driving motor is connected with the side guide rail through a driving roller; an inner cylinder and an outer cylinder are arranged above the rotary disc chassis base; a heating air pump is arranged in the inner cylinder; a detachable top cover is arrangedabove the inner cylinder and the outer cylinder; wire arranging devices are arranged on the two sides of the rotary disc chassis base; and tractors are arranged at the outer ends of the wire arranging devices. Compared with the prior art, the submarine cable tray degassing chamber has the beneficial effects of being simple in structure, convenient to use and operate and capable of greatly improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of submarine cable manufacturing, in particular to a degassing chamber for a submarine cable tray. Background technique [0002] XLPE insulated submarine cables, due to the material characteristics of the insulating material itself, will produce by-products such as acetophenone and methane during the vulcanization process. These tiny impurities are distributed in the insulating layer in a free state. After completing the three-layer co-extrusion process in the process, the semi-finished insulated wire core needs to be put into the degassing chamber for degassing treatment, so that the by-products can be quickly volatilized and discharged, and the stress concentration, micropores, insulation defects, etc. that are easily caused by electric trees are eliminated. , aging, breakdown and other failures. [0003] Considering the characteristics of the continuous length, large length and high weight of the submari...

AI Technical Summary

Problems solved by technology

[0004] 1. It is only suitable for the degassing of medium-voltage submarine cable insulated cores with a voltage level of 35kV and below. When producing ultra-high voltage insulated cores with a voltage level of 110kV and above, it takes about 40 days to achieve the degassing effect. low efficiency

[0005] 2. Applicable to the cross-section specification of a single 800mm 2 Insulated wire cores below 1000mm 2 When degassing treatment is carried out for large cross-section wire cores with a diameter of 100000000000000000 and above, the by-products are not volatilized sufficiently, and the degassing effect is not good

[0006] 3. Set up an air supply port and an air outlet respectively. The flow of hot air in the degassing chamber is poor, the air distribution is uneven, and there will be "gathering areas" and "deficiency areas". Insufficient degassing results in gas micropores, affecting product quality
