Ted Meng,sales manager Int'l Dpt,10th,Sep,2016
Dry type bushing
with silicone rubber insulator
and RIF(resin impregnated fibre)
IEC 60137 Ed 6.0 & GB/T 4109-2008
24kV through 252kV ,100A through 31500A
Compare to OIP Bushing
lRaduce the risk of fire
lOil leakage is eliminated
lMechanically rigid design and no need oil supervision
lSeals the transformer and reduces the down time in the
event of major TFO failures
lLightweight and compact,less than 50% of OIP
lEasy transport and stored,installed at any angle
lCan be energized immediately after installation
RIP VS OIP
Slicone rubber insulator
l Reduced maintenance
l Hydrophobic surface
l Reduced leakage currents
l Longer cleaning intervals
compared to porcelain
l Improved safety
l Non shattering
l Non flammable
l Increased seismic withstand
l Self extinguishing when
exposed to open fire
Why dry?Why silicone rubber?Why RIF?
lNo oil to leak
lNo oil to contaminate
lNo oil to burn
lNo pressure vessel to rupture
lHigh seismic performance
lWide applicaion worldwide
fire caused by oil
A. The products are absolutely solid structure without oil or gas,no need
for maintenance and will not leak oil or gas.
B. The insulation margin of the bushing is large and they use the
semiconductor as the capacitive screen which improves the corona
inception voltage greatly.
C. They are made of refractory and insulation material which will not
decompose. Their electric property is stable and there will be no danger of
combustion and explosion,needless to say any damage to other
equipment during operation.
D. The products are with a compact construction ,the silicon rubber
umbrella are small in size and with a light weight,which is easy for safe
transport and they can be installed at any angle.
E. The products are twined by epoxy glass fiber and use optimal
mechanical layer tay-up design.With a high flexing resistance and
excellent. mechanical property,they are especially suitable for heavy
earthquake area for its anti-seismic conditions (g≤1).
F. The material characteristics of products determines that they can resist
great changes of temperature between 155 ℃ and ﹣200 ℃.
G. The antifouling property of silicon rubber bushing is excellent and the
products are widely used in area with heavy pollution.
H. Benefits from above advantages, we can guarantee own a longer
service life and lower cost for long-time running than the traditional oil
I. With a short production cycle,the product can be designed and produced
according to different operating requirements of customers,in a fast and
