Ideally suited for Control
and Relay Panels or equipment Control Panel
(instrument panel etc.) in the floor mounted
version or Lighting DBs, Remote Control
Stations etc. in wall mounting versions.
These are simple cabinets with properly
laid out and wired switchgear inside. All
wiring is in PVC ducts and cable terminations
are on vertical rows of terminals. Floor
mounted version either has a fixed front
sheet or hinged doors. Bolted structure
with mounting flexibility is also a popular
option for floor mounted version..
This is a classic two
tier design ideal for distribution boards,
a central busbar chamber is flanked by one
tier of modules at the top and the other
tier at the bottom. Cable terminations for
bottom tier are in front and those for top
tier are at the back. Extendable on both
sides. Back access a necessity.
horizontal busbar chamber placed at the
top or at bottom. Common cable alley placed
on opposite side of busbar chamber (bottom
or top) depending on cable entry requirement.
Boards extendable on both sides. Economical
design. In which wires from BBC to modules
and those from modules to cable alley, pass
through intervening modules.
Problem of wires passing
through intervening modules is solved in
this design by providing wire ways between
two vertical columns of modules. All wires
from BBC to modules and those from modules
to cable alley pass through these wireways.
This is a very popular design for MCCs,
that combines economy of type TA1 and extra
reliability of unitised designs type TU.
Type TA 2 is other version in TA design
and has a vertical busbar chamber and
a vertical cable alley with modules sandwiched
in between. These are not extendable but
have feature of cable entry both from
top or bottom
of line design in fixed type compartmentalised
switch boards and MCCs. These are of unitised
design. Each of the units has a horizontal
busbar chamber at the top or bottom. A vertical
busbar chamber at the side (TU 1) or back
(TU3) of each unit and a unit cable alley
at the back (TU1) or the side (TU3) of each
Both TU 1 and TU3 have to have back access,
the dead front version in this design
(with no back access) has vertical busbars
on one side of module and unit cable alley
on other side and is designated as TU2.
All vertical busbars on one side of module
and unit cable alley on other side and
is designated as TU2. All designs in TU
series are extendable on both sides.
enclosures are fabricated from good quality
steel sheet of thickness 10/14/16 swg as
per design requirement. Structural members
of panels are designed to withstand electrical
and mechanical stresses that are encountered
by switchgear. Enclosures can be provided
with degree of protection up to IP 55. Enclosures
are offered with liquid paint or powder
coat and shades as per requirement . Elaborate
quality checks are ensured at every stage
of fabrication & painting. Flexible
Cu wire of appropriate size and colour code
is used for wiring with printed ferrule
as per international standard. Cu or AL
busbar of electrolyte grade with PVC heat
shrink sleeve used as per specification.
DMC/SMC/Epoxy resin cast support used with
careful design to meet short circuit requirement
up to 50 KA.
