Indoor 24kV power cable termination kits
Product description:
1. All products conform to IEC 60502, GB12706.4 standards and passed type tests of national authority organization, safe and reliable with long-term operation.
2. Import DESMA liquid injection production system to ensure quality stability of product.
3. Product design methods and ways has achieved international advanced level, also meet the operation under various working conditions.
4. Each batch of raw material have been pass the mechanical performance index spot check, which ensure product quality from the source.
5. All finished products 100% will need to passed factory performance test (power frequency withstand voltage, partial discharge).
6. Years of experience in installation and operation, professional engineering installation team, can provide on-site installation and guide product installation.
7. Cold shrink technology (spiral support bar), convenient and reliable installation.
8. Big pressing force and persistence on mating interface.
9. Big expansion rate, long storage period after expansion, ensuring retraction to reach the designated position.
10. Non-magnetic constant force spring to permanent connect to ensure a good contact for long period without vortex.
11. Separately earthing for armor and copper shield.
12. Imported silicon rubber to maintain long period storage after expansion; 2 years guarantee period, avoid the condition like domestic rubber Retraction does not reach the designated position.
13. Imported high-performance grease to avoid moisture absorption and blending and ensure the safety of interface.
14. Imported liquid silicone rubber materials processing, excellent heat resistance, cold resistance, dielectric properties, resistance to ozone and atmospheric aging properties.
