Product Range
Power & Distribution
Transformers from 25 KVA to 5000 KVA upto 33 KV.
Standard MUSKAAN'S transformers are designed
and tested as per IS : 2026, BS - 171, IEC - 76 & IEC - 726.
Vector Group Transformers will be connected as
per vector group reference Dyn 11. Other vector groups can be offered as
per specific requirements.
Terminal Arrangement H. V - Bare Bushings or Cable Box,
L. V-Bare Bushings or Cable Box. Disconnecting
Temperature Rise MUSKAAN'S transformers are designed
for a maximum temperature rise of 40/50 degree C of oil/winding. Lower
temperature rise can be offered on request.
Core The core is constructed from low
loss, cold rolled, grain oriented, annealled lamination of electrical
sheet steel conforming to the latest international standards. Special
frame is built-in-house for clamping the core to reduce the magnetic
noise as well as making the whole structure rigid and robust.
Windings Coils are wound with electrolyte
high conductivity paper covered or synthetic enamelled copper
conductors. Cooling ducts are provided to keep the hot spot temperature
as low as possible. Coils are dried in electric ovens. Rigid connection
support and coil clamping is provided to ensure high shot circuit
strength.
Insulation Pecompressed board PARMALI Board and
JAPANEESE insulation paper of best quality is used.
Tapping A. OFF CIRCUIT TAP CHANGING
SWITCH Tappings from + 5% to - 5% in steps of 2.5% for HV
variation or as per customer's requirement.
B. ON LOAD TAP CHANGER 16 steps OLTC for HV variation from + 5% to - 15% in steps of 1.25% or as per specific requirements. OLTC for remote/auto/parallel operation can also be offered. Oil Oil is tested for resistively,
dielectric and acidic characteristic conforming to IS - 335. Before
topping up oil is filtered thoroughly.
Tanks The tanks are made of M.S. steel
plates / sheets with adequate bracing & stiffness. Tanks are
pressure tested to withstand any type of inside or outside pressure. All
the external surfaces are given a primary coat of zinc chromate, red
oxide and two finishing coats of grey paint. The inner surfaces are
given a coat of heat and oil resisting paint.
Quality Control and Routine Tests All MUSKAAN'S transformers undergo
rigorous quality control checks and are routine tested as per IS in our
fully equipped laboratory. Any specific test required by the customer
can also be arranged. |
