Product Description

6~35kv Cable Accessories Classification Introduction
Explore our range of cutting-edge cable solutions: 4E-NLS Cold Shrinkable Indoor Termination, 4E-WLS Cold Shrinkable Outdoor Termination, and 4E-JLS Cold Shrinkable Joint. These innovations ensure unmatched reliability and performance in all settings.
The 4E-NLS cold shrinkable technologyindoor termination, and the 4E-WLS cold shrinkable solutionoutdoor termination, along with the 4E-JLS cold shrinkablemiddle joint, form an integral part of our advanced electrical solutions. These components are mainly composed of a prefabricated body, terminations (catering to both indoor and outdoor needs) or connecting tube (middle joint) cold shrinkablemulti-core fingerstall (ideal for supporting multi-core cables), and cold shrinkableinsulation tubes along with relative colormetric tubes (suitable for both indoor and outdoor termination). The prefabricated body stress cone and insulating body leverage the precision of plastic injection molding using liquid silicone rubber, ensuring the long-term stability of the package's tight force and a uniform electric field capacity. It consistently maintains an optimal radial pressure to the cable body, with excellent interface characteristics that prevent respiration creepage breakdown during cable operation. The terminations or connecting tubes are meticulously designed to meet cable core material requirements as well as user specifications, ensuring comprehensive protection of cable insulation and waterproofing.

Main Structure Features:
Premium raw materials: Our prefabricated bodies are crafted from high-quality liquid silicone, delivering outstanding insulation, elongation, and breakdown properties, with minimal residual deformation post-expansion.
Cold shrinkablestructure: Utilizing the latest expansion equipment and support tubes, we ensure flawless product expansion without any damage.
Effortless installation: The cold shrinkableexpansion structure requires no specialized training, reducing labor costs with its straightforward, convenient installation.
