167Kva Single Phase Pole Mounted Transformer Step Down 12.47KV Oil
Immersed ANSI IEEE Standard Power Overhead Distribution Transformer
WINLEY’s single-phase, oil-filled, pole-mounted distribution
transformers are designed for servicing residential overhead
distribution loads. They are also suitable for light commercial
loads, industrial lighting and diversified power applications.
These transformers are designed for the application conditions
normally encountered on electric utility power distribution
systems.

Standard Features
- Lifting lugs
- Arrester mounting pads
- High-voltage porcelain bushing(s) with eyebolt terminals
- Low voltage bushing insulators are available in fiberglass
reinforced polyester material or porcelain (both eyebolt and spade
terminals)
- Low-voltage neutral grounding strap (furnished on 10 – 50 kVA
single HV bushing units)
- ANSI support lugs (hanger brackets)
- Cover has 15 kV dielectric insulation and increased resistance to
corrosion. The cover is sloped 15°, preventing water from
collecting and thereby reducing the chances of corrosion and
leaking.
- Self-venting and resealing cover that eliminates the need for an
auxiliary pressure-relief device and offers increased safety
through higher tank withstand
- Wound core with step-lap joints for increased efficiency and lower
noise levels.
- Core/coil bolts in pads are 180° apart
- Embossed low-voltage leads
- Oil fill-plug
- Cover ground-strap
- Tank ground-pad
- Primary protective link
- Surge arrester
- Secondary circuit breaker
- Secondary breaker operating handle with emergency overload reset
- Laser-etched, anodized, aluminum nameplate with bar-coded serial
number
