Raychem -Busbar Insulating Tapes

Medium Voltage Heat Shrink/ Fusion tapes. HVBT heat-shrinkable tape is ideal for use on complex shapes and where busbars cannot be disconnected.

Raychem busbar insulating tape is a specialized electrical insulation material used to enhance insulation and protection of busbars (conductive bars used in power distribution systems). It is widely used in switchgear, substations, and panel boards.

Description :

Raychem busbar insulating tape (such as HVBT / LVBT types) is typically a heat-shrinkable, adhesive-coated insulating tape designed to wrap around busbars and provide reliable electrical insulation and environmental protection.

Key Features :

• Heat-shrink technology
  The tape shrinks when heat is applied, tightly conforming to the busbar shape.
• Adhesive lining
  Inner adhesive melts during heating, bonding overlapping layers to form a sealed insulation.
• High dielectric strength
  Provides strong insulation and protection against electrical flashover (up to ~36 kV depending on type).
• Flexible & wraparound design
  Suitable for complex shapes and locations where busbars cannot be dismantled.
• Non-bonding to metal
  Adheres to itself but not to metal, allowing easy removal for inspection.
• Indoor & outdoor application
  Resistant to environmental conditions, UV, and tracking.

Types of Raychem Busbar Tape :

1. HVBT (High Voltage Busbar Tape)

• Used for medium/high voltage systems (up to ~36 kV)
• Heat-shrink type with adhesive coating

1. LVBT (Low Voltage Busbar Tape)

• Used for low voltage systems (≤ 1 kV)
• General-purpose insulation for compact installations

1. MVFT (Self-amalgamating tape)

• Cold-applied silicone tape
• Layers fuse together to form a solid insulation barrier

Applications :

• Busbars in switchgear panels
• Substations and power distribution systems
• Cable joints and terminations
• Retrofit insulation where dismantling is difficult

Advantages :

• Improves system safety and reliability
• Prevents flashover and accidental discharge
• Easy installation compared to rigid insulation
• Suitable for maintenance and retrofit work

Simple Definition :

Raychem busbar insulating tape is a heat-shrinkable, adhesive-lined electrical tape used to insulate and protect busbars from flashover, environmental effects, and accidental contact in power systems.
