Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the descriptions involving "first", "second" and so on in the present invention are only for descriptive purposes, and should not be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one f...

Abstract

The invention discloses a cable connection construction process, which comprises the following steps of: sleeving an intermediate joint on a pretreated cable core in advance, then fusing and welding the cable cores at two ends together in a welding mold, moving the intermediate joint to the welding position of the two cable cores, and clamping and fixing, so that the connection of the two cables can be realized; and finally, restoring and burying the cable underground to complete the laying work, so that the process is simple, and the laying efficiency is high. According to the technical scheme, the problems that in the prior art, an existing cable welding and laying technology is complex, a cable connection structure is not firm, and the transmission capacity is reduced are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of cable connection, and relates to a cable connection construction technology. Background technique [0002] With the clarification of the goal of "carbon peak, carbon neutrality", new energy projects will maintain a long-term high-speed development trend. Power cables are an important part of the wind and solar power collection lines, but they are easy to error occured. Due to the thick insulation layer of the 35KV aluminum alloy cable, the electric field between the intermediate joint and the insulation layer will be highly concentrated, which will bring great difficulties to the safe operation of the direct buried cable. [0003] Existing cable joints can be divided into three types: strip-wrapping type, cold-shrinkable type and heat-shrinkable type. According to the analysis and comparison of actual faults in the field, the above three types of cable joints all have the problem of high failure rate. I...
