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. HVBT tape shrinks 30% longitudinally and an adhesive layer flows and seals the layers of tape during installation. As with the other components in the system, the adhesive does not bond to metalwork, allowing easy removal for inspection and maintenance. Available in four widths from 25 mm to 100 mm. A spiral formed tape is also available for ease of use on overhead conductors. MVFT is a self-amalgamating tape providing insulation enhancement and protection against accidentally induced discharge. Quick and easy to install, upon application the tape amalgamates the overlapped layers together, producing a complete seal.

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
2. LVBT (Low Voltage Busbar Tape)
   • Used for low voltage systems (≤ 1 kV)
   • General-purpose insulation for compact installations
3. 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
