Crosslinked polyethylene cable crosslinking equipment

Abstract

The invention provides crosslinked polyethylene cable crosslinking equipment, and belongs to the field of power equipment. The crosslinked polyethylene cable crosslinking equipment comprises a heat preservation box body with a box door on one side, a cable reel arranged in the heat preservation box body, and hot air supply equipment arranged outside the heat preservation box body, wherein the hot air supply equipment comprises a hot air outlet; the cable reel comprises a horizontally-arranged reel and two circular plates fixed to the two ends of the reel respectively; the reel is made of a heat conduction material; the reel is in a hollow shape; the two ends of the reel are opened; a pipeline with an outlet and an inlet is arranged between the hot air supply equipment and the heat preservation box body; the pipeline comprises a straight pipe right facing the reel; the inner end of the straight pipe extends into the heat preservation box body and is connected outside the reel in a sleeved mode; inner cavities of the straight pipe and the reel are communicated; a port of the inner end of the straight pipe is an outlet; an inlet is communicated with the hot air outlet; a locking structure capable of automatically locking the reel is arranged in the straight pipe; and locking of the straight pipe by the locking structure can be unlocked outside the heat preservation box body through external force. According to the crosslinked polyethylene cable crosslinking equipment provided by the invention, the crosslinking quality can be improved.

Description

technical field [0001] The invention belongs to the field of electric power equipment, and relates to cross-linked polyethylene cable processing equipment, in particular to cross-linked polyethylene cable cross-linking equipment. Background technique [0002] In the cross-linked polyethylene cable preparation process, the cable extruded by the extruder is only a semi-finished product, which needs further cross-linking to transform it from a linear structure to a network structure. During this cross-linking process, high temperature is usually used Pool or high-temperature steam room, but due to the pressure in the high-temperature pool or high-temperature steam room, water easily enters the conductor layer, causing the conductor to oxidize. [0003] For the above problems, people have realized the shortcomings and made improvements, such as a hot air device (application number: 202021150419.2) for the crosslinking of silane crosslinked polyethylene cables disclosed in the Ch...

AI Technical Summary

Problems solved by technology

However, there is still a problem with this device: when heating, the contact surface between the outer side of the cable and the hot air is much larger than the inner side of the cable, resulting in different degrees of crosslinking between the inner and outer sides of the cable, which affects the quality
