High-Voltage Electrical Insulation Solutions
High-voltage electrical networks demand resilient sealing components to prevent moisture ingress and flashovers. Hangda Electric manufactures Cold Shrink Cable Accessories engineered for 26-35kV distribution networks. Installing a modern cold shrink cable system eliminates heat torches, reducing fire hazards and installation errors in challenging field environments.
Product Performance and Technical Specifications
Mechanical and Environmental Sealing
Hangda silicone rubber formulations maintain constant radial compression across fluctuating conductor temperatures. The active elasticity provides continuous weatherproofing for exposed terminals.
-
High Dielectric Strength: Withstands electrical stress exceeding 25 kV/mm without breakdown.
-
Hydrophobic Surface: Prevents conductive leakage paths forming in damp underground vaults.
-
Durable Protection: Heavy-duty cold shrink cable end caps seal abandoned wire ends against grit and water infiltration.
Technical Parameters
| Parameter | Specification |
|---|---|
| Operating Voltage | 26/35 kV |
| Insulation Material | Liquid Silicone Rubber |
| Dielectric Strength | ≥ 25 kV/mm |
| Tensile Strength | ≥ 10.5 MPa |

Sourcing and Cost Considerations
Installation Versatility
Each full-set cold shrink cable jointing kit contains pre-stretched elastomeric sleeves mounted on removable plastic cores. Pulling the internal core allows instant radial shrinkage without specialized thermal tools.
-
Fast Deployment: Slashes field labor time per junction.
-
Consistent Quality: Uniform wall thickness guarantees reliable electric field distribution.
Commercial Value
Evaluating the cold shrink tube price involves assessing material longevity, reduced maintenance downtime, and direct factory pricing from Hangda Electric.
