Heat Shrink Bus Bar Sleeve Manufacturer – MV & HT Busbar Insulation Solution
Heat Shrink Bus Bar Sleeves are premium electrical insulation tubes designed to protect copper and aluminium busbars from short circuits, flashover, dust, moisture, and accidental contact. When heated, the sleeve shrinks tightly over the busbar, forming a durable, flame-retardant insulating layer.
Our Heat Shrink Busbar Sleeves are widely used in Medium Voltage (MV) and High Tension (HT) electrical systems including switchgear panels, substations, transformers, and power distribution boards.
These sleeves provide reliable insulation, improve personnel safety, and extend equipment life in demanding electrical environments.
Voltage Range
• MV Heat Shrink Busbar Sleeve – up to 36kV
• HT Heat Shrink Busbar Sleeve – 36kV to 72.5kV (custom available)
Suitable for new installations and retrofit projects.
