Short answer: cold shrink accessories install without flame and give stable radial pressure, while heat shrink accessories are common for cost-sensitive projects where trained installers and heat tools are available.
| Cold shrink | Fast installation, no flame, good sealing pressure and useful for live project schedules with strict safety rules. |
|---|---|
| Heat shrink | Lower cost and widely available. Requires controlled heating and experienced installation. |
| Outdoor use | Confirm UV resistance, creepage distance and sealing design for both types. |
| Storage | Cold shrink has shelf-life and core removal considerations. Heat shrink needs proper storage to avoid deformation. |
Use cold shrink when installation speed, flame-free work and consistent pressure are more important than the lowest unit price.
