1.0 Product Description
1.1 General
The 3M
™
Industrial Loadbreak Elbow connector is a
fully-shielded and insulated plug-in termination for
connecting underground cable to transformers, switching
cabinets and junctions equipped with loadbreak bushings.
The elbow connector and bushing insert comprise the
essential components of all loadbreak connections. The
5810 Series kits are designed for use on tape shield, wire
shield, UniShield
®
and jacketed concentric neutral types
of power cables.
The loadbreak elbows are molded using high quality
peroxide-cured EPDM insulation. Standard features
include a coppertop connector, tin plated copper loadbreak
probe with an ablative arc-follower tip, stainless steel
reinforced pulling-eye and a capacitive test point.
Wide cable ranges are sized to accept cables insulated at
either 100% or 133% insulation levels within a given
conductor size. The wider cable ranges increase
installation flexibility.
The coppertop compression connector is a standard item
to transition from the cable to the loadbreak probe. An
aluminum crimp barrel is inertia-welded to a copper lug.
The aluminum barrel makes the connector easy to crimp
and the copper lug ensures a reliable, tight, cool operating
connection with the loadbreak probe.
1.2 Installation
Cable stripping and scoring tools, available from various
tool manufacturers, are recommended for use when
installing loadbreak elbows. After preparing the cable and
installing shield adapter, the elbow housing is pushed onto

the cable. The loadbreak probe is threaded into the
coppertop connector using the supplied installation tool or
an approved equivalent. Use a shotgun stick to perform
loadmake and loadbreak operations. See installation
instructions for details.
