Product Details
Intermediate cold shrink couplings for voltage 110 kV are ready-made insulating products designed for connecting cable lines with voltage 110 kV. They provide elastic shrinkage thanks to cold shrink technology, providing reliable insulation, sealing and mechanical protection. Their main characteristics include low maintenance, ease of installation and a high degree of adaptability, allowing them to be widely used in tunnels, substations and other places.
Main models and technical parameters
Core cross-section: from 150 mm² to 1600 mm².
Rated voltage: 64/110 kV.
Lightning impulse withstand voltage: 550 kV (10 times for each positive and negative polarity).
Ambient temperature adaptation range: -40 °C to +50 °C.
Installation method: Suitable for use in tunnels (if immersed in water, fiberglass casing and sealant must be used).
Key points of installation
Installation must be carried out by professional personnel to ensure an even cut of the metal protective layer without burrs and to avoid damage to the heat shrink material. Particular attention should be paid to waterproofing.
Applications
Suitable for highly reliable power supply networks such as municipal power grids, industrial power transmission and distribution systems and others.
