Connection details

Solid rod is used for maximum current capacity and
stranded cable for greater ease of assembly, when the
required current capacity is lower. A mounting kit is used for
fixing and sealing the terminal to the bushing.

Mounting kit

The mounting kit, LF 170 087-A, is supplied with each
bushing and consists of a divided ring, a divided spring
washer, two O-rings and a top nut. One of the O-rings is
intended for use at site installation.
Included in each packing for delivery are two lifting eye bolts
M12, 2183 2001-3, and a hook spanner, 6896 743-1, intended
for use at installation.

Integrated inner/outer terminal

The integrated inner and outer terminal is available with
different inner diameters suited for different stranded
cables. Other configurations can be supplied on request.
