Steema Heat Shrink Bushing Angle Boots (11kv & 33kv)
Insulating Boots For Switchgear & Transformer Bushing & Termination Connections
At Steema Transformers & Electricals (U) Ltd, we provide high-performance heat shrinkable bushing boots designed for essential electrical insulation in medium voltage applications. Our STEEMA-STU series are specifically engineered to enhance the creepage distance between live metal parts and surrounding earthed metalwork, as well as between neighboring phases within switchgear and transformer bushing compartments, and cable termination boxes.
These heat shrink boots are ideally suited for systems operating at 11kV and 33kV, offering robust insulation solutions.
The cable terminations can be energized immediately after the installation of our bushing boots, which also boast an unlimited shelf life. Our bushing boots are designed for a perfect fit and provide superior protection for all types of indoor Cold Shrink or Heat Shrink cable terminations.
Applicable Voltage Levels:
Each STEEMA-STU kit comprises 3 heat-shrinkable bushing boots and insulating mastic, provided as complete sets for 3 phases.
- 6/10 (12) kV (for 11kV systems)
- 6.35/11 (12) kV (for 11kV systems)
- 8.7/15 (17.5) kV (for 11kV systems)
- 21/35 (36) kV (for 33kV systems)
- 26/35 (36) kV (for 33kV systems)
