RAYCHEM BPTM 24KV BUSBAR INSULATION TUBING
Description
BPTM is a medium wall, heat-shrinkable tubing which provides insulation enhancement and protection against flashover and accidentally induced discharge. Particularly useful in confined spaces BPTM tubing can be used on both circular and rectangular copper or aluminium busbars. On application of heat the tubing
shrinks snugly over the busbar profile ensuring that the required minimum wall thickness is obtained. BPTM tubing can be installed easily during large scale production using an oven or in the field using a gas torch or hot air. BPTM tubing is manufactured from a non-halogen based polymer which has excellent performance in high voltage environments and greatly reduces the noxious and corrosive effects in fire situations.
Applications
The use of BPTM tubing allows equipment designers the freedom to reduce air spacing between busbars, such as in the manufacture of switchgear cabinets where space is at a premium. BPTM provides flashover protection up to 25 kV.
Features/benefits
• Compatible with all other products in the Raychem MV insulation enhancement system
• Excellent flexibility, can be installed on a wide range of curved or bent busbars without cracking or creasing
• High shrink ratio reduces inventory and simplifies product selection
• Exceptional insulation and long term reliability even at high continuous operating temperatures
• Extremely durable, resists damage from solvents, ultraviolet light, weathering, mechanical impact and general wear and tear
• Suitable for indoor and outdoor use
• Excellent anti-tracking properties
• Good thermal emissivity and contact with busbars means no derating is required
• Flame retardant and non-halogen based material reduces flammability and the toxic and corrosive effects in fire situations
• Can be stored indefinitely at temperatures up to 50 °C without loss of performance
• Over 30 years of successful operating experience
