Introduction
1. Installation Preponderance
The W (N) LS-24KV/35KV cold shrink termination is applicable for either indoor or outdoor applications. This selection of cable termination adopts state-of-the-art cold shrink technology, and is designed with elastomer that will immediately stick to installation part once the conductor core inside the cold shrink terminal is extracted.

2. Material Superiority
We fabricate this cold shrink termination using superior silicone rubber insulation and German Dow Corning sizing material. Therefore, this product comes with merits like high elasticity, excellent leakproofness, good corrosion resistance and wonderful hydrophobicity.

3. Structural Advantage
This range of cold shrink terminations is designed in pre-expanded structure. It can maximally cover conductors and requires no fire or friction for installation, making for installation convenience and low cost.

Meanwhile, the one-piece stress control unit and terminal bushing, fabricated via injection molding, is designed in geometrical shape, effectively relieving electric filed stress concentration degree at the end of cable semiconducting layer. If three-core cable is used, we can provide you cold shrink insulating tube and unique three core pull-over tabs.

Distinctions between Indoor and Outdoor Types Cold Shrink Terminations
Whereas there is less pollutants indoors, the indoor cold shrinkable terminal comes with smaller blade. While, the outdoor type is designed with larger blade considering that there are more pollutants outdoors and also there is need for increasing security creepage distance.

Reference Standards
Our cold shrink terminations are made conforming to IEC60502, IEEE48 and GB/T12706 standards.

Application
1. You can apply this cold-shrink termination to 24KV/35kV XLPE single-core or three-core copper or aluminum conductor cable with 50-400mm2 sectional area.
2. This product is also applicable for cable with extrusion-type semiconducting layer for shielding.
3. It functions well in highly polluted, salty, foggy and humid areas, or in regions with high temperature differential.
