Na stránkáchIndoor Cold Shrink Cable Terminationis an advanced solution for low- and medium-voltage cable installations, providing seamless insulation and environmental sealing without the use of heat. Ideal for indoor environments, this termination method offers improved safety, simplified installation, and long-lasting performance.
What Is a Cold Shrink Termination?
Cold shrink terminations consist of pre-expanded, silicone rubber insulating components mounted on removable plastic cores. During installation, the core is pulled out, and the elastic material shrinks tightly around the cable. Unlike heat shrink solutions, cold shrink does not require torches or heat guns, making it especially suited for confined, moisture-sensitive, or flammable indoor environments.
Applications
Indoor cold shrink terminations are commonly used in:
- Electrical switchgear rooms
- Power distribution boards
- Industrial automation enclosures
- Utility substations (indoor zones)
- Data centers and telecom hubs
This product is compatible with XLPE and EPR insulated cables across various conductor sizes and voltage classes (typically 1kV to 36kV).
Market Trends and Industry Adoption
Cold shrink technology has steadily replaced traditional heat shrink methods in indoor installations due to its safety, speed, and reliability. According to IEEE studies, cold shrink reduces average installation time by 40–60% and improves sealing consistency. Major utility providers and industrial OEMs—including ABB and Schneider Electric—have adopted cold shrink as a preferred termination method for indoor applications.
Wikipedia notes that elastomeric terminations are less prone to installation defects and require less training, contributing to reduced downtime and failure rates.
