The
KDSU Range
of Cable Glands is suitable for
armoured or unarmoured cables and
comprises:
.
threaded entry body, including
a
groove
to accommodate
an optional O-ring seal, which tightens into an
associated enclosure
.
silicone or neoprene
sealing
ring,
which fits into the entry body
to
provide
a flameproof seal around the inner
sheath of the cable
.
armour ring and
armour cone to clamp onto armour/screen/braid
(when
applicable to installation),
compression nut
and skid
washer.
The compression nut with
the skid
washer
compressing the seal onto the
inner
sheath of the
cable,
minimising
cable twist upon assembly
.
mid-cap for
coupling
internal
locking mechanisms
onto the entry body
.
outer cap,
skid
washer
and silicone or neoprene
elastomeric sealing ring. The cap tightens
onto the
mid-cap
whilst
compressing the seal onto the outer sheath
of the cable and a skid washer minimising
cable twist upon
assembly. The elastomeric
sealing
ring
also being available in red with
a
reduced
bore
Glands are available in
the size
range
16 to 100 mm with ISO metric
entry threads of M20 to M100 respectively.
Specific
type design option:
.
Cable
glands
fitted with neoprene
flameproof elastomeric
sealing
rings may
be
fitted with
a brass continuiÇ
washer
in the 20S to 100
sizes that are used with lead inner sheathed
cables,
glands
with
this
modification
are designated with an 'L' in
their type number.
The
KISU Range
of Cable Glands is suitable for
armoured or unarmoured cables and varies from the KDSU by:
.
the replacement
of outer cap, skid washer and
outer sheath elastomeric seal with an alternative cap
tightening onto
the entry body component
o
rot having
the option
to be
