Introducing Froment 8000 S
ERIES
Load Banks
The 8000 S
ERIES
load banks are currently the largest capacity self-contained load banks
supplied by Froment. In standard form they are Sigma controlled, combined (resistive/
reactive) load banks with capacity ranging from 3300 kVA (8300) to a maximum of around
6000 kVA (8400). The 8800 is also a combined unit but has an integrated transformer to
load test High Voltage (HV) supplies.
All units are housed within custom-made ISO standard intermodal shipping containers.
The 8300 is contained within a 10ft container, the 8350 in a 15ft container and the 8400
and 8800 within a 20 ft container. All sizes are fitted with standard ISO twistlock lifting and
fixing points and are supplied with CSC certification for top-loading shipping. The 8400 is
also fitted with pad eyes to provide a conventional four-point lift.
The units are of all steel construction and are insulated to minimise condensation. The
internal cabinets are manufactured from corrosion resistant, zinc-plated mild steel using
the Froment standard construction method.
The resistive elements are mounted in the top half of the duct and forced-air cooling for
them is provided by a pair of axial fans mounted in the lower section. The load section is
combined with a control room containing all of the switchgear and operating controls for
the load bank. A side entry door allows personnel to enter the control room.
The air inlet louvres are fitted with steel mesh grills and the outlet ducts are fitted with
stainless steel mesh screens, both of which provide protection to IP1X. Optional air inlet
louvre covers can be fitted to provide environmental protection during transport.
In the control room all of the electrical and electronic components are housed behind
recessed doors, which are fitted with seals that provide protection up to IP54.
