16 SAFEGEAR® 5/15 KV, UP TO 50 KA ARC-RESISTANT SWITCHGEAR
The design of the cable compartments for SafeGear
provides an efficient layout with ample room for
stress cones and a choice of cable terminations and
lug types. Customers also have the flexibility of top or
bottom cable entry. Top and bottom connections can
also be made to bus duct.
In two-high arrangements with stacked circuit break-
ers, steel barriers separate the upper and lower cable
compartments to isolate the primary circuits. All con-
figurations come standard with lug boots and have
the option for cable supports to make field connec-
tions more secure.
Cable compartments are available with optional read-
ily accessible zero sequence (ground sensor) current
transformers, surge arrestors or capacitors and/or
ground studs on the bus risers. When a draw-out fuse
compartment is installed in the front of the switch-
gear, the rear cable compartment offers room for a
large three-phase floor-mounted control power trans-
former up to 75 kVA.
Primary cable compartments are provided with re-
movable, non-painted stainless steel cover plates
used to install conduit or cable sealing glands.
12-gauge type 304 stainless steel is used in
Safegear for the cover plates. Cover plates are re-
quired for top and bottom of the cable compart-
ment. All conduit/cable entries must be sealed to
prevent arc-faults from leaking through the instal-
lation at the cover plates. ABB recommends the use
of sealing glands for all primary cables to ensure
arc-resistant design integrity is not compromised.
