MBSM Wrap Around Jacket Repair (to 35kV)MBSM repair sleeves (heat shrinkable) protect cables in mechanically abusive environments. They also rejacket premolded splices. MBSM also repairs and rejackets LC shielded and moisture impervious cables. MBSM is also used to provide strain relief to cables.
MBSM is available in five different sizes; all supplied with a 5:1 shrink ratio (that is a high, high shrink ratio). It is designed to be used on standard poly or elastomeric insulated / jacketed cables which may include aluminum or steel armoring. MBSM provides a moisture vapor transmission barrier for repairing and rejacketing LC shield and moisture impervious cables. MBSM sleeves do not provide electrical insulation.
