3m Cable Joint description – 91-AV
3M Scotchcast 91-AV resin inline cable joint kits are supplied with a two part translucent mould body for simple and easy handling.
Distances inside the cable joint body can be checked easily.
All necessary dimensions including application range, cable preparation are given in the detailed jointing instruction.
The two foam sealing elements can be adapted to the required cable diameter by removing the pre-cut adapter rings.
The joint mould body can be adapted to the required cable diameter by cutting the marked areas of the mould.
Scotchcast resin 2131 is delivered in a two chamber bag and aluminium Guard Bag for protection against humidity.
The re-openable seam and integrated spout with a membrane provides a 3M Closed, Mixing and Pouring (pictured) cable jointing system.
After the seam of the two chamber bag is opened, the Scotchcast resin components can be mixed.
To pour the cable joint resin into the mould body the bag has to be cut open by the jointer.
To provide Scotchcast resin handling without any skin contact, disposable gloves meeting EN394 are provided with the joint kit. The 3M Closed Mixing and Pouring System provides resin handling without any skin contact – for protection against pollution, a closure cap is applied onto the dome. After curing, the remaining cable joint resin in the bag can be disposed as household waste.
