Heat shrinkable wraparound delivery system for air blocking of pressurized telephone cables BH-RSDA
- Applications: BH-RSDA Heat shrinkable wraparound delivery system for air blocking of pressurized telephone cables which is made of super-sleeve material, which combines the strength and durability of composite design with proven heat-shrink technology. Sleeve material is composed of several layers of specially blended polymers and adhesives, a fiber-reinforcing layer. Used with suitable commercially available resins, the BH-RSDA system forms a pressure block for the whole pressurized cable range.
-
Characteristics: High performance heat shrinkable closure for pressurised applications;
Just few sleeve sizes will accommodate single or double sheath cable with diameters from 0.4 to 0.6mm;
Provides high mechanical strength;
Applicable for polyethylene and metal jacketed cables;
Pre-installed valve for pressure access and measuring;
Up to 3 cables at each end can be accommodated using three finger clips with hot-melt adhesive. - Operating temperature range: Minimum fully recovery temperature: 120oC
- Approvals / Specifications: RoHS
- Colors: Black
