This article summarizes the causes of the common problems of high-voltage cables as follows: High-voltage cable joints have previously been used in wrap-around, die-cast, and mold-type types. The workload required for on-site production is large, and due to the limitations of on-site conditions and the manufacturing process. Because of this, air gaps and impurities are inevitably present between insulating tape layers, so problems are apt to occur. The types that are commonly used in China are assembled and prefabricated.
The cable joints are divided into cable end connectors and cable intermediate joints. No matter what the joint type is, the cable joint failure usually occurs at the fracture of the cable insulation shield because it is the location where the electrical stress is concentrated and the cause of the cable joint failure due to manufacturing reasons is stress. Cone body manufacturing defects, insulation filler problems, oil leaking seals and other reasons.
The cable grounding system includes the cable grounding box, the cable grounding protection box (with protective layer protector), the cable cross-interconnect box, and the cover protector. The general problem that is easy to occur is mainly because the poor sealing of the box body leads to multi-point grounding, causing the metal sheath induction current to be too large. In addition, the selection of protective layer protector parameters is unreasonable or the quality of the zinc oxide crystal is unstable, and it is easy to cause damage to the protective layer protector.
The first branch factory of Tianjin Cable Factory was established in 1972. It is specialized in the production of mining communication cables, communication optical cables, RS485 dedicated communication lines, computer cables, super five cable lines, control cables, shielded cables, and mine flame retardant explosion-proof Cables, audio signal cables, communication cables, local telephone cables, Category 6 network cables, mine network cables, mining control cables, airport lighting cables, photoelectric composite cables, shielded twisted pair cables, steel wire type armored cable manufacturers. Welcome your call!
All the fabric have the Grey Scale Level 5 performance under the xenon-arc lamps with the condition ISO 4892-2:2013 cycle 1.
