Tyco MXSU and SXSU Joints

Medium Voltage Heat Shrink Joints

Tyco MXSU

The Tyco MXSU heat shrink joint system is designed for 11kV and 33kV straight joints for single core non-armoured polymeric cables with mechanical connectors.

MXSU is based on a complete product concept

• Mechanical connectors for conductor and wire shield are supplied with the kit
  
• Kits are widely range taking and cover most conductor constructions including their tolerances
  
• No crimping tools or tool maintenance required
  
• Short and space saving design for installation
  
• Improves installation reliability
  
• Has unlimited shelf life, simplifies material logistics and reduces cost
  
• Avoids bulky waste and costly waste disposal
  
• Exceeds international performance standards including CENELEC HD 629 for joints and IEC 61238-1 for mechanical connectors

MXSU joints passed all tests for XLPE insulated cables according to CENELEC HD 629.1 S1 including impact tests at ambient and at low temperature.

MXSU joints were subjected to additional tests which are not part of any European standard but reflect future demands in modern network operation: Overload operation of cables: More than 800 hours of electrical heat cycling at conductor temperatures of 130 °C with a voltage of 2.5 times the operating voltage U0. Oversheath testing as the routine test method of cable networks: Voltage withstand tests between the screen wires and the water bath for 15 minutes at 15 kV DC and at 8 kV AC.

Mechanical connectors used in MXSU joints, pass the requirements in accordance with IEC 61238-1 class A.

Tyco SXSU

The Tyco SXSU heat shrink joint system is designed for 11kV and 33kV straight joints for single core non-armoured polymeric cables without mechanical connectors.

MXSU Features:

• Widely range taking and short design
• Excellent sealing abilities due to elastomeric technologies
• Covers most crimp connector sizes and technologies
• Advanced heat shrink behavior due to triple extrusion technology
