Elpress Screw connectors for low and medium voltages
The
Elpress screw connectors are intended for stranded and solid
aluminium and copper cables, carrying low and medium voltages of
up to 36 kV. The range covers cross-sectional areas of 10-630
mm˛ for round cable and 16-240 mm˛ for sector cable.
Connection to the conductors is achieved by tightening the
screws in the through connector or terminal to a predetermined
torque. Tightening takes place into a partially threaded nut.
The tightening torque is correct when the screw breaks at its
notch. It does this thanks to an innovative double-ended
shear-off screw, as shown in the illustration.
Elpress Connectors made of aluminium and copper
Through connectors and terminals are made of aluminium, and the
accompanying screws are of brass to reduce friction and
facilitate installation. The terminal palm is made of copper.
The through connectors have an intermediate wall to enable
jointing of oil-filled cables to plastic-insulated XLPE cables.
The screw connectors meet the requirements of IEC 61238-1.
To facilitate installation there is a holding tool, ISL2201.
Washer solution
Elpress Screw connectors are supplied in closed plastic
packaging with clear installation instructions. By applying the
accompanying screwed joint washers for the screw connectors, the
terminal palm can be used for two screw sizes.
