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
