Cable accessories customers to consult, few questions are often asked to summarize where I do some small hope to provide some small help our customers purchase. 1, cable accessories? A: electric attachments indirect cable terminal junction boxes, cable junction box, connecting tube and terminals, steel wiring trough, cable trays. 2, what cable joints? A: connecting cable and the cable conductors, the insulation shield layer, and a protective layer, so that the cable line connection means, known as the cable joints. Heat shrinkable cable accessories Features and Benefits What is it? A: The most important feature of the heat shrink cable accessories is to stress the tube instead of the traditional stress cone, it not only simplifies the construction process, and also reduced the size of the connector terminal, easy installation, saving time and labor, superior performance, saving metal. Heat shrinkable cable accessories set perfusion and dry-inclusive as a whole, the collection of the advantages of these two attachments. 4 What are the advantages of cross-linked heat shrinkable cable accessories? A: This is a new type of material, and now other types of attachments with excellent electrical performance, small size, quality, and ease of installation, supporting materials, and etc., and also has a weather-resistant, anti filthy, fire-retardant, self-extinguishing capacity. The above describes some basic knowledge of cable accessories, Let's talk about a few common questions: What is the insulation strength? A: The insulation material in an electric field, when the electric field strength increases to a certain limit will be breakdown, this result in insulation breakdown electric field strength is called the dielectric strength. 2 What are the requirements for the mechanical strength of the connection point of the cable conductor? A: The mechanical strength of the connection point, typically less than the tensile strength of the cable conductor itself, For fixed laying a power cable, the connection point of the tensile strength requirements of not less than 60% of the tensile strength of the conductor itself. 3, power cable insulation material should have the main performance? A; should have the following performance: ◆ high breakdown strength ◆ insulation performance of long-term stability; ◆ low dielectric loss; ◆ a relatively high insulation resistance; ◆ excellent resistance discharge performance; ◆ with a certain degree of softness and mechanical strength; . Brief 10KV XLPE cable heat shrinkable cable accessories produced indoor terminal head? A; 1) preparation phase: check whether heat shrinkable cable accessories are available, model whether there is a match, check to make sure the cables for tidal, check cable. 2) removal of excess cable, the cable length is determined according to the situation. 3) stripping the sheath. 4) welding the ground line, the ground wire is welded to the steel strip. 5) fill Sanchakou and wrapped sealant. 6) install three core branch jacket, the jacket sleeve into the roots began to shrink from the middle finger, first to the roots, and then further. 7) peel the Copperbelt and outer semi-conductive layer, peel cut three core branch looper 20mm Copperbelt, non-injury main insulation, cleaned semi-conductive layer. 8) Install the stress tube, part of the support sets of docking heat shrinkable tube port side. 9) Install the terminals. 10) Install insulated pipe. 11) Install the gland. 12) installed after the nuclear phase-phase color tube.
