GuangJu middle 10KV three core oil power cables

 Specializing in the production of shrink / shrink cable accessories, European plug head, European cable branch box, American cable branch box, 10KV single (three core) Shrink Cable Joints, 10KV three core oil intermediate connection [JLS] 10KV three Oil central core cables ?? intermediate heat shrinkable cable accessories below voltage XLPE cable or cable and the oil terminal. Compared with traditional cable accessories with small size, light weight, safe, reliable, convenient installation. Products meet GB11033 standards, long-term use temperature range of -55 ℃ ~ 105 ℃, aging life of 20 years, radial shrinkage ≥50%, longitudinal shrinkage of <5%, the shrinkage temperature of 110 ℃ ~ 140 ℃. The material is generally a polyethylene, an 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 (1010-1012Ω? Cm), 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 stress along the tube into a more uniform distribution. This technique can only be used in 35kV and below cable accessories. Because stress tube heat was not working voltage level is high. Its use in key technical problem: To ensure the electrical parameters of the stress pipe must meet the predetermined reference value in order to * work. Also note that using grease filled cable insulation the semi-conductive layer of the fracture gap to exclude gas, to reduce partial discharge purposes. XLPE cable because internal stress occur when handling bad running large contraction, which pay attention to stress pipe and insulation shield put up less than 20mm during the installation accessories, to prevent the contraction stress from the tube and the insulating shield. Shrink annex because less flexibility may cause thermal expansion and contraction when the operation generated at the interface gap, thus sealing technology is important to prevent moisture ingress.
