  • Designed for specialist cable applications where hydrocarbons are present in offshore locations

HAZARDOUS AREA ZONES

  • Zone 1 – according to ATEX a place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.
  • Zone 2 – according to ATEX a place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is not likely to occur in normal operation but, if it does occur, persists for a short period only.

3M Scotchcast Hazardous Area joint kits include the new flame-retardant, hydrocarbon-resistant, halogen-free 1402FR resin packs.

3M Scotchcast Hazardous Area cable joint kits are designed for use with both single-core and multi-core armoured power cables up to 3.3kV – this new 3M product features a unique hinged mould body and totally enclosed mixing system which is suitable for use in areas of high soil contamination and ATEX rated hazardous areas.

The 3M Scotchcast LVI-3/x range replaces the traditional Scotchcast LR range of cable joints and is designed for use with both Cembre type copper through connectors (compression splices) or mechanical shearbolt connectors, the two smallest 3M joints LVI-3/2C and LVI-3/3C being supplied with mechanical connectors to suit multi-core cables.

  • High-performance 2-part polyurethane 1402FR hazardous area cable jointing resin
  • Suitable for use with wire armour (AWA and SWA) cables and wire braid (GSWB) cables
Cable Connectors

3M Electrical Cable Joints – for conductor jointing either Cembre (Crimp) or Pfisterer Sicon (Mechanical) style connectors can be used depending on application and Jointer preferences.

Although cable joints are not formally certified according to ATEX there are several minimum specification and performance requirements for cable joints when being used to connect, repair or joint cables in hazardous areas.

For example 3M LVI-3 type cable joints include specially formulated 3M Scotchcast 1402FR resin – this cable jointing resin is hydro carbon resistant, flame retardant, halogen free and chemical resistant for use in hazardous area locations.
