MPG-10 10 kV Heat Shrinkable Continuous Busbar Insulation Sleeve
MPG-10 10 kV Heat Shrinkable Continuous Busbar Insulation Sleeve
Product Application
MPG-10 Series is designed for insulation and protection of 10 kV busbars in switchgear, busbar trunking systems and distribution boards.
Supplied in continuous lengths, the sleeve can be cut on site to the required size. It provides electrical insulation, improves phase-to-phase
and phase-to-earth clearances, and helps prevent accidental contact and short-circuit faults.
Product Features
• High flame retardancy: oxygen index greater than 30
• Good heat resistance: suitable for continuous operation at temperatures up to 105℃
• Excellent low-temperature performance: remains flexible without brittleness or cracking at -55℃
• Good flexibility: easily conforms to complex busbar shapes and is convenient to install
• High electrical insulation: allows reduced phase-to-phase and phase-to-earth clearances
• Easy phase identification: available in three standard colors – red, yellow and green
• Enhanced safety: helps prevent faults and accidents caused by short circuits or inadvertent contact by personnel or small animals
