Flame retardant cable type performance and advantagesOrdinary flame retardant wire and cableOrdinary flame-retardant wire and cable insulation and sheathing materials are generally made of halogen-containing (or modified with halogen-containing flame retardants) polymer materials, the most commonly used is polyvinyl chloride (PVC) material...
According to a recent announcement by international market research firm Technavio, the global overhead cable market share is expected to increase by US$17.67 billion from 2022-26, growing at a compound annual growth rate of 5.1% during the period.One of the key factors driving the growth of the overhead cable market is the increase in renewable energy g...
Several issues should be noted when choosing to use control cablesIn order to ensure the control cable in the event of insulation breakdown, mechanical damage, or fire, and reduce the scope of the spread, the national standard GB50217-91 "Power Engineering Cable Design Specification" stipulates: dual protection current, voltage, and DC power s...
Discuss the knowledge of power cable structureThe power cable generally consists of a core, an insulating layer, and a protective layer. The core is used for conducting electricity; the insulating layer is used to insulate the core conductor from the protective layer to prevent leakage; the protective layer is used to prevent damage to the cable in...

Description of the main causes of wire and cable insulation ruptureBreakdown refers to the damage of the insulation layer of the cable due to external force damage (extrusion, lightning strike, etc.), the deterioration of the insulation material, etc., the original insulation performance is destroyed, the original insulation performance is lost, an...
Control cable head production and secondary wiring methodsWith the widespread use of computer technology, the number of control cables is increasing. For example, two sets of units with more than 300 MW have nearly 1,000 km of control cables, more than 20,000, and 200,000-300,000 cores. If the control cable head is not beautifully produced...
Description of the use and performance of the control lineThe control cable should meet the requirements of GB/T9330-2008. 450/750V PVC insulated control cable, flame retardant PVC/XLPE insulated control cable and refractory PVC/XLPE insulated control cable.450/750V polyethylene insulated control cable meets the requirements of GB/T9330-2008...
Cable line fault causes and solutionsShort-circuit fault: There are two-phase short-circuit and three-phase short-circuits, which are mostly caused by hidden dangers left in the manufacturing process.Grounding fault: A certain core or several cores of the cable break down to the ground. The insulation resistance is lower than 1...
