Raychem Medium Voltage Fusion Tape

Raychem

TE Connectivity’s (TE) Raychem Medium Voltage Fusion Tapes are self-amalgamating, providing insulation enhancement and protection against accidentally induced discharge. The design aims to combine the integrity of silicone polymers with the versatility of wraparound products.

Our Raychem MVFT tapes are quick and easy to install. When applied, the tapes amalgamate the overlapped layers, producing a complete seal. A single MVFT layer, two-thirds overlapped, will provide AC voltage withstand (flashover protection) to at least 15 kV, increasing to 35 kV if a second layer is applied. Although the tapes will stick to themselves and other insulating materials, they will not adhere to metal or porcelain, for easy removal and maintenance.

Our Raychem MVFT tapes offer a simple and effective solution to the challenges of retrofit insulation of busbars, particularly where existing equipment cannot be dismantled. They can be used for indoor and outdoor applications and installed on different shapes, including complex connections.
