3M Heat Shrink MV Termination Kit offers reliability and flexibility to meet the demands of cable network operators. The terminations are available for 11, 22 & 33 kV. The components of the kit are designed for conditions where the terminations are exposed to rainfall, outdoor sunlight, extremes of weather and heavily polluted areas. The specially engineered kits also take care of the typical partial and surface corona discharge for all power cables under challenging service conditions.

All the heat shrinkable components are supplied in an expanded state and would shrink effectively on application of heat.

• Anti-tracking/Lug Sealing Tubes to meet the outdoor conditions & performance requirements of medium voltage power cable end terminations. The material resists to splitting and has excellent arc resistance. These tubes are flexible, conforms to shapes/core bends, halogen free, self-extinguishing and suitable for both outdoor and indoor applications.
• Stress Control Tubes to provide electrical stress grading and relief on screen interruptions, which avoids localised stress accumulation leading to failures. 3M SCT tubes are made from specially formulated Polyolefin and provide good balance between electrical and mechanical properties.
• Lug Sealing Tubes to protect the interface between the termination lug and the cable core covered with the non-tracking MV tube.
• Lugs to provide high-performance connections.
• Cleaning Solvent Pouches to clean the XLPE insulation surface.
• Worm Clips to ensure good electrical connection.
• Tinned Copper Braid to protect conductive wiring from interference and handling large current and low voltage.
• Stress Control Mastic to be applied on the connector and semi-conducting screen to fill all the gaps and uneven surfaces.
• Sealing Mastic, conformable and durable mastic with excellent moisture and environmental seal used for sealing medium voltage cables and accessories and covering sharp edges.
• PVC Insulation Tape, thermally compatible to insulate electrical wires and other materials that conduct electricity. Use as markings on the joint construction.
• Ferrules to protect against damage, splitting or wear.
• Black Sealing Mastic, conformable and durable mastic with excellent moisture and environmental seal used for sealing medium voltage cables and accessories and covering sharp edges.
• Tartan tape – GU Vinyl Tape to provide primary electrical insulation for all wire and cable terminations with pressure-sensitive rubber-based adhesive.
• Stress Grading Mastic, a water-resistant adhesive applied on connectors and cable components, used in MV joints to provide stress relief of the electric field.

3M offers termination kits suitable for single-core 66 kV, 630 sq mm indoor cable terminations, primarily utilizing heat-shrink or cold-shrink technology to provide reliable insulation and stress control. 

Product InformationThe specific product details and availability for a 3M termination kit for 66 kV, 630 sq mm, single-core, indoor applications can be found through various suppliers and online platforms.

• Technology: 3M manufactures both heat-shrinkable and cold-shrinkable termination kits for high-voltage applications. Cold shrink technology is often preferred for its ease of installation without the need for a flame and constant radial pressure on the cable.
• Key Components: The kits typically include components for stress grading, insulation, and sealing.
  • Stress Control Tubes/Mastic: These components manage electrical stress at the screen interruption point to prevent localized accumulation and potential failure.
• Anti-tracking Tubes: These tubes are designed to resist tracking and arcing, suitable for indoor applications where specific environmental conditions must be managed.
• Lugs and Connectors: The kit usually accommodates high-performance lugs to provide secure conductor connections.
• Environmental Sealing: Specially developed sealants protect the termination from moisture and contaminants.
