Cembre MT-TD and MT-GC connectors are high voltage copper through connectors designed to joint, splice and connect conductors in high voltage cable applications up to 33kV – the high voltage connectors are manufactured from high purity copper, annealed and tin plated and compatible with both Cold Shrink and heat shrink cable joints.
Cembre MT-GC connectors feature a solid stop (“blocked”) which forms a moisture barrier between the two conductors being jointed, this prevents the migration of oils or greases, which may be present, in one cable contaminating the other LV MV HV cable – applications include transition cable joints or splices where existing Paper Insulated Lead Covered (PILC) are jointed onto new polymeric (XLPE EPR) insulated cables up to 33kV.
Cembre MT-TD connectors are unblocked and are suitable for joining cables of the same insulation type – this includes polymeric-to-polymeric type straight through connections on Low Voltage (LV), Medlium Voltage (MV) and High Voltage (HV) cables up to 33kV with XLPE or EPR type insulation.

11kV PILC Cables – paper insulated cables impregnated with oil should be transition jointed using “blocked” type Cembre MT-GC connectors to prevent contamination of polymeric cables when connecting to XLPE EPR insulated cable.
➡ Video Demonstration: Medium Voltage Heat Shrink Transition Joint
When jointing XLPE to PILC cables at medium voltage, 11kV/33kV, it is recommended to use “blocked” type connectors when splicing and jointing stranded copper conductors on transition applications where paper-to-polymeric cables are to be jointed – for dissimilar type conductors and connecting copper to aluminium cables a shearbolt connector can be used.
