The Mining Industry and the Use of Cable Coupler Systems
In mining operations, surface or underground, trailing cable/connector
systems are typically used to supply power to moveable equipment.
Where high voltage and large fluctuating currents are used throughout
the mine site, safety, economics, and reliability are a priority.
Safety is very important while handling power cables and the couplers
that connect them. The UEE system is designed under CAN/CSA M421
by incorporating a pilot pin arrangement that opens first and makes
last and a ground connection that opens last and makes first. This
ensures that the supply circuit breaker is not operated until the
phase contacts make and the body of the coupler is connected to
ground.
UEE couplers require minimal insertion effort for a complete connection
or disconnection to be made. A quick, eye-bolt locking system provides
a secure and watertight seal. These features, along with others,
make the UEE Couplers convenient to use by providing maximum flexibility,
thus reducing downtime and improving overall economics.
Reliability of this system was achieved by basing design features
on experience with field cable repair. Potential features and benefits
were identified and incorporated into the coupler design.

FEATURES & BENEFITS |
|
APPLICATION |
|
Quality, sand-casted aluminum body makes the coupler
durable and light
No exposed phase conductors in the bell cover eliminates
the need for cavity filling
Stainless steel bolts with no exposed locations ensures
reliable disassembly
Forged, stainless steel eyebolts provide a "no failure"
bolting arrangement
O-ring joints and modified rubber gaskets make the coupler
assembly entirely weather proof
One piece high strength insulator is formed from the
latest technologically advanced plastics to provide the
best electrical and flame extinguishing properties
Arrangement of main phases separated by a continuous
ground shield ensures that should faults occur they are
phase-to-ground not phase-to-phase, therefore, reducing
the possibility of damaging high energy failures
Silver-plated, copper pin & socket assemblies are
designed for optimum current and heat transfer properties
with low insertion resistance
Positive and secure cable/connector connections eliminate
the need for soldering
Pilot pin connector assembly ensures a secure, low-resistance
path through the coupler
Optional extended body provides additional space to accommodate
larger cables
Kirk-key interlock on female receptacle allows equipment
isolation
