Thermal products 10kv heat shrinkable power cable accessories

?? 10kv 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 inner insulating sealing guide tube temperature: -50 ℃ → 105 ℃ under the 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 indoor terminal, outdoor terminal, intermediate connection, an oil user terminal, oil terminal and oil outdoor intermediate connection; (2) products for the three core; (3) Model 10-16mm2 to 300-400mm2. Notes: 0 stands for the cable 10-16mm2 1 stands for the cable 25-50 mm2 2 stands for the cable 70-120 mm2 3 stands for the cable 150-240 mm2 4 stands for the cable 300-400 mm2 10KV 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) 45KV no flashover, no breakdown 45kv, 1min, combination wet state and a sample without flashover Breakdown PARTAIL DISCHARGE TEST partial discharge test 13KV power decentralization is not greater than 20PC A, B, C three-phase power at 13kv delegated to 2pc 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 105kv, positive and negative polarity 10 times no flashover, no breakdown 105kv the polarity of the 10 times, a combination of trial No flashover and breakdown like DC NEGATIVE POLARITY VOLTAGE WITHSTAND FOR 15MIN 52kv no flashover, no breakdown 52kv, 15min, a combination of a sample without flashover and breakdown AC WITHSTAND TEST FOR 4H 4H 35kv power frequency voltage test no flashover, No breakdown 35kv, 4h, a combination of a sample without flashover and breakdown
