Jiangsu amounted to win cjds35kv factory direct thermal electric cable accessories

?? 35kv heat shrinkable power cable accessories features: (1) light weight, reliable operation, easy installation (2) shrink quickly, without cracking (3) cross-linked heat shrinkable cable terminations, the first double-ground processes. Namely steel and copper ground wire armor shield is separated from ground, full of more reasonable pre-cable (4) cross-linked heat shrinkable cable intermediate connection of new technology (three sealing process). Cable Joints failure because many are caused by bad seal, the first to adopt new technology (three sealing process), the cable running more secure. The so-called three seals that is outside the door seal layer, indoor layer sealed together at both ends of the tube within the insulating sealing temperature guidelines:? At -50 ℃ → 105 ℃ temperature conditions of long-term use. Application range: products are widely used in electric power, petrochemical, metallurgy, railway, port and other buildings. Product Specifications: (1) products are mainly classified into user terminals and cables in the cable outside the terminal; (2) Products at single, three-pin; (3) Model 10-16mm2 to 150-240mm2 Notes: 1 stands for the cable 25- 50 mm2 2 stands for the cable 70-120 mm2 3 stands for the cable 150-240 mm2 35KV heat shrinkable power cable accessories technical parameters (outdoor terminal) PROPERTY TEST METHOD Test Project Test Method Test Results RESULT AC WITHSTAND FOR 1MIN UNDER RAIN 1MIN frequency voltage (wet) 105KV no flashover, no breakdown 105kv, 1min, wet under a combination of a sample without flashover and breakdown PARTAIL DISCHARGE TEST partial discharge test 39KV decentralization of power is not more than 20PC A, B, C three-phase at 39kv decentralization of power to 4pc HEATING CYCLES VOLTAGE TEST load cycle test conductor is heated to 90-95 ℃, each cycle of 8h, wherein the heating 5h, cooling 3h, a total of three cycles required to complete three standard load cycle test IMPULSE VOLTAGE WITHSTAND TEST impulse voltage test 25kv, the polarity of the 10 times without flashover, no breakdown 25kv positive and negative polarity 10 times, a combination of a sample without flashover and breakdown DC NEGATIVE POLARITY VOLTAGE WITHSTAND FOR 15MIN 156kv no flashover, no breakdown 156kv , 15min, a combination of a sample without flashover and breakdown AC WITHSTAND TEST FOR 4H 4H 104kv power frequency voltage test no flashover, no breakdown 104kv, 4h, a combination of a sample without flashover and breakdown
