Problems solved by technology

There is an active interface between the stress cone cable accessories and the cable main body insulation, and the active interface contains complex factors such as air gap, micro water, impurities and insulating grease, which can easily lead to air gap discharge along the surface and space accumulation of charges. The local electric field is distorted, which eventually leads to insulation breakdown, which restricts the safe operation of the cable system

Embodiment Construction

[0013] The manufacturing process of the present invention is used to overcome the problem of electric field distortion at the stripping and cutting part of the semiconductive layer of the cable main body terminal, and prevent this part from being broken down; this part mainly performs several aspects of work: the melting and crosslinking process of the factory insulating layer and the filling insulation; Melt crosslinking process of factory semiconducting layer and filled semiconducting layer; melt crosslinking process of filled insulating and filled semiconducting layer. After the above work is completed, the injection molding process of the stress control module can be completed. After the above process is completed, the production of the cable terminal head is further carried out.

[0014] Specifically, such as figure 1 As shown, according to the requirements of the production process, the outer sheath and metal sheath at the cable terminal are stripped and cut, the outer s...

Abstract

The invention discloses a manufacturing process of a cross-linked polyethylene insulated cable main terminal molding stress control module. The manufacturing process comprises the steps of fusion cross-linking between a cable factory insulating layer and a filling insulator, fusion cross-linking between a cable factory semiconducting layer and a filling semiconducting layer and fusion cross-linking between the filling insulator and the filling semiconducting layer. The manufacturing process is convenient to operate; the manufactured stress control module and a cable body form an integrated structure; the electrical property of electric field stress distribution is stable, the problem that a movable interface is generated because a cable and the stress control module are made of different materials is solved, and the problem of breakdown of cable insulation as a result of local electric field distortion of the insulating layer caused by accumulative charge in the space of an insulating border is avoided. The manufacturing process breaks through the technical bottleneck in the industry internationally that an extra-high voltage direct current cable is free of terminal connection, and meets the requirements for submarine cable and alternating current and direct current high-voltage / extra-high-voltage cable terminal project field fabrication and fault repair.

Description

technical field [0001] The present invention relates to the process technology set by the injection stress control module of the main body terminal of cross-linked polyethylene insulated cables, which is suitable for high voltage and ultra-high voltage of AC 66kV to AC 500kV, and direct current ±10kV to ±500kV cross-linked polyethylene insulated cable main body terminal molding On-site fabrication process of the stress control module. Background technique [0002] The electric field at the terminal of the traditional AC 66kV to AC 500kV high voltage and ultra-high voltage, DC plus or minus 10kV to plus or minus 500kV cross-linked polyethylene insulated power cables will produce distortion. A stress-controlled design is required. Up to now, the whole world has made considerable achievements in the technical field of cable terminal stress control, and correspondingly designed accessories have also been put into the market. The stress control in these accessories is pre-produ...
