Mechanical Lugs and Connectors

Mechanical Lugs and Connectors

Mechanical lugs and connectors are a reliable and efficient solution for connecting power cables or other energy devices. They are suitable for cables of various cross-sections and materials, with applications up to 35 kV.

Various Connections

• Copper Conductors:

Copper Conductors

• Copper Conductors:

Aluminium Conductors

The connections must transmit electrical energy – means high current – during the whole lifetime without negative influence on joints, terminations and plugs concerning their thermal, mechanical and insulation behaviour.

Mechanical Lugs and Connectors2

Oil Blocking:

• Ensures proper conductor positioning
• Isolates oil leakage when connecting PILC conductors

Bolt and Insert:

• Double layers of shear-off-head interacts with the insert allows a big span-range application

Body:

• Made of high strength, tin-plated aluminium alloy

Groove:

• Indented groove and insert improve electrical and mechanical performance

Mechanical Connectors versus Crimping Connectors

Mechanical Connectors versus Crimping Connectors2

No special tools for installation, only a socket spanner or a wrench is needed.

Heavy crimping tools and a lot of different dies are necessary.

Only 5 sizes cover conductor cross-sections from 1.5mm² to 1000mm².

For every cross section, a specfic crimping connector is needed.

Are adapted to the cross section range of the accessories.

A copper conductor needs a copper connector.

Copper and aluminium conductors, which could be round or sectoral shaped, stranded or solid, can be connected.

An aluminium conductor needs an aluminium connector.

Easy installation. Torque design provides easy installation of the bolts.

Complex installation.

After installation, the length and outer diameter will not change.

After installation, connector body will be stretched a little.
