The 6~35kV cable accessories include 4E-NLS Cold Shrinkable Indoor Termination, 4E-WLS Cold Shrinkable Outdoor Termination, and 4E-JLS Cold Shrinkable Joint. These products are designed to provide reliable and efficient solutions for cable termination and jointing in both indoor and outdoor environments.
Prefabricated Body: The core component, made through plastic injection molding of liquid silicone rubber, ensures long-term stability, uniform electric field distribution, and consistent radial pressure on the cable body. This prevents issues such as respiration creepage breakdown during cable operation.
Terminations (Indoor/Outdoor) or Connecting Tube (Middle Joint): Designed to meet cable core material specifications and user requirements, these components ensure effective insulation protection and waterproofing.
Cold Shrinkable Multi-Core Fingerstall: Supports multi-core cables and ensures a secure fit.
Cold Shrinkable Insulation Tubes and Colorimetric Tubes: Provide additional insulation and identification for indoor and outdoor terminations.
High-Quality Materials: The prefabricated body is manufactured using premium liquid silicone rubber, offering excellent insulation, elongation, and breakdown resistance. It also exhibits minimal residual deformation after expansion.
Cold Shrinkable Design: Utilizes advanced expansion technology and support tubes to ensure the product expands smoothly without damage.
Ease of Installation: The cold shrinkable structure eliminates the need for specialized training, reducing labor costs and simplifying the installation process.
4E-NLS Cold Shrinkable Indoor Termination: Ideal for indoor cable termination in environments where space and environmental conditions are controlled.
4E-WLS Cold Shrinkable Outdoor Termination: Suitable for outdoor applications, providing robust protection against weather and environmental factors.
4E-JLS Cold Shrinkable Joint: Designed for connecting cables in the middle of a run, ensuring seamless insulation and mechanical strength.
These cable accessories are engineered to deliver superior performance, durability, and ease of use, making them a reliable choice for 6~35kV cable systems.
