More Information
Product family SRBB
Main description Heat shrinkable medium wall tube
Sub description protection for busbar systems and reduction of minimum clearance
Family description The heat shrinkable tubes type SRBB are medium-walled, without thermoplastic adhesive with a shrinkage ratio of 3:1. Typical applications are medium voltage substations up to 36 kV as well as suitable for corrosion protection.
Notes A standard spool may include sections which have been tied together., Other lengths available on request.
Characteristics Medium wall, Stabilized against UV rays, Halogen-free, Tracking resistance, Non-corrosive, Resistant to bacteria and fungi, Free of lead and cadmium, Silicone free
Applications Allows for clearance reduction between busbars in medium voltage substations up to 36 kV
