Tee Connectors - Medium Voltage



Nexans Euromold tee connectors are designed for terminating high voltage XLPE insulated power cables into compact switchgear to make optimum use of limited installation space.

Nexans, a worldwide leader in the cable manufacturing and accessory industry, has extended its well-proven range of compact high voltage (HV) connectors with two new tee-shaped connectors designed specifically for use with compact switchgear and transformers now being specified for wind turbine applications.

The Nexans Euromold M430TB connector is for use with higher voltages (33kV-36kV) and the M434TB connector is for higher currents (up to 1,250A).


  • Trend Towards Compact Switchgear for Wind Turbines

The growing trend towards using ever more compact high voltage switchgear in wind turbines has resulted in smaller cable termination and junction boxes, limiting the space available for jointers to install Nexans cable connectors.

Nexans has responded to this challenge by developing asymmetric tee-shape connectors to create a compact connection solution. This now enables two medium voltage cables to be connected in the same space required for one cable using a traditional non-compact connector. As well as being ideal for all applications where space is a limiting factor, the Nexans compact connectors also enable users to increase the capacity of an existing installation.

  • EPDM Rubber Jacket: A Key Design Feature for Safety and Reliability

The Nexans Euromold M430TB and the M434TB are separable tee-shape bolted connectors designed to connect high voltage polymer-insulated cable to wind turbine equipment such as switchgear and transformers- they can also be used for cable to cable connections with the appropriate mating parts. A key design feature is the thick (3mm) EPDM (Ethylene Propylene Diene Monomer) rubber conductive insulation jacket that provides a total safe to touch screen for personnel safety, this is both more reliable and longer lasting than the painted silicone rubber insulation used in many connectors.

  • Nexans M430TB : Almost Twice As Compact As A Traditional Connector

Nexans Euromold M430TB cable connector is suitable for voltages from 11-12kV up to 33-36kV and cable cross-sections from 35sqmm up to 300sqmm (11-12kV and 24kV) and 50sqmm up to 240sqmm (33-36kV). When used as a single connector the Nexans M430TB is only 183mm deep, this compares with 255mm for an equivalent non-compact connector.

For double-connection, the epoxy insulating plug can be replaced by the Nexans 300PB coupling connector - this enables two cables to be connected in a depth of only 290mm, compared with 500mm for a non-compact medium voltage cable connector.

  • Nexans M434TB : Specifically Designed For Larger Wind Turbines

Nexans Euromold M434TB connector is also 183mm in depth, however it is intended for the larger cross-section cables that will be required to carry the greater currents produced by the new generation of larger turbines, especially in offshore applications. For voltages from 11-12kV up to 33-36kV, the Nexans M434TB can be used with cable cross-sections from 185sqmm up to 800sqmm.
