Cable maintenance requirements and methods currently used in low-voltage cable accessories more products than the main types of heat shrinkable accessory, prefabricated annex, cold shrink accessories. They are the following features: a heat-shrinkable material is generally used in the annex to polyethylene, ethylene - vinyl acetate component of a variety of materials (EVA) and ethylene-propylene rubber blend composition. These products mainly deal with electrical stress pipe stress concentration problems. That parameter control method using an electric field to alleviate the stress concentration. The main advantage is lightweight, easy to install, the performance is still good. Cheaper prices. Tube is a volume resistivity of moderate stress (1010-1012Ωocm) Nanyang cable manufacturers, a large dielectric constant (20 - 25) special electrical parameters of heat shrinkable tube, forcing the use of electrical parameters of the cable insulation shield the fracture stress evacuation into the tube along the stress more evenly distributed. This technique can only be used in 35kV and below cable accessories. Because heat stress tube voltage level is high and not work reliably. Its use in key technical problem: To ensure the electrical parameters of the stress pipe must meet the predetermined reference value can only work reliably. Cabling (1) Cable Transit: Cable should be wound on the plate transport cable, manpower should promote the turns along the cable wrapped around the direction of the arrow on the tight direction or disc marked scroll, which will cause loose, wrapped twist, after actinomycetes difficult . When the car transport, cable tray should stand up to the car and temporarily fixed. When unloading the disc throwing allowed to roll down along the springboard or hanging down. Large cable drum roll relatively difficult, it is best to use a forklift to move. Short cable can be rolled into a predetermined minimum bend radius circle, four points tied tight after handling. Cabling is currently laying artificial, only with a special tool. When the cable laying, cable trays in cable line the shelves, cable tow partially disposed plastic or aluminum to tackle, placed on the cable pulley, cable can not only reduce labor intensity, but also to reduce cable friction on the ground to protect cable from damage. After the cable laying in place, timely finishing cable Nanyang cable prices, the cables are arranged according to the design position to place cable straighten, according to specification with plastic tape or cable card lashing, and promptly suspended cable card, the cable should have the following cards: cable number, cable type, size, start and end points, etc. At the following locations should be linked to the cable brand: both ends of the cable, the cable change direction at the corner, the cable shaft opening, cable intermediate joint. Nanyang cable prices, Fu Long electricity (certified), cable provided by Nanyang Fu Long Electric Power Engineering Company Limited. Nanyang Fu Long Electric Power Engineering Co., Ltd.
