Pad Mounted Transformer 3 Phase 1000Kva 34.5Kv to 208V Radial Feed
Ceramic Sleeve oil immersed power transformer
Winley electric's 1000 kVA three phase pad mounted transformer
stepping 34.5 kV down to 208Y/120 V with multiple tap positions for
flexible voltage adaptation.
A standout feature is the high‑quality ceramic high‑voltage
bushings, which provide superior pollution and flash‑over
resistance, enhanced mechanical strength and long‑term dielectric
stability—reducing maintenance and extending service life.
WINLEY Electric's three-phase pad transformers are UL/CUL certified
and comply with ANSI/IEEE/DOE/CSA standards, with fast delivery
within 7-35 days.

Advantages of Pad Mounted Transformer
Advantages of Pad Mounted Transformer
1. Space-Saving Design
Pad-mounted transformers feature a compact, high-efficiency design,
making them an ideal choice for locations with limited available
space. They eliminate the need for additional supporting structures
such as utility poles or dedicated buildings during installation.
2. Underground Installation Capability
Unlike overhead transformers, pad-mounted transformers can be
installed underground—delivering a safer and more unobtrusive
solution for power distribution. This underground placement also
reduces their vulnerability to environmental hazards and damage.
3. Enhanced Safety Standards
Pad-mounted transformers are engineered with tamper-proof and
robust security features. Housed in a durable metal enclosure, they
completely eliminate the risk of accidental contact with live
electrical components.
4. Superior Aesthetics
Pad-mounted transformers typically integrate seamlessly with their
surrounding environment, positioning them as a more suitable option
for residential communities and areas subject to strict zoning
regulations.
