No-heat joints with waterproof mastic and armour band.
| Models | JLS |
|---|---|
| Voltage class | 10-35 kV |
| Standards | IEC 60502-2, GB/T 12706 |
JLS are cold shrink straight joint kits that install without any heat source. The pre-stretched body collapses onto the cable when the core is removed, while waterproof mastic and an armour band restore sealing and mechanical continuity.
The kits suit wet trenches, underground vaults and hazardous areas where torches or hot-air tools are impractical or forbidden.
| Model | Cable Cores | Conductor (mm²) |
|---|---|---|
| Standard | Single/Three-core | 25-400 |
| 10 kV class | Single/Three | 25-630 |
| 35 kV class | Single/Three | 50-630 |
Standard color: black. Custom colors available — contact our sales team.
Waterproof mastic seals the joint against standing water. Installs without heat even in flooded or damp excavations.
No open flame or hot-air gun needed during installation. Suitable for zones with flammable gas or dust where heat sources are banned.
Confined joint bays and cable basements benefit from slip-on installation. No generators or power tools to move into position.
