75KVA Three Phase Pole Mounted Transformer Oil Immersed 13800V to 480V
WINLEY Electric's three-phase pole-mounted round water tank is designed for areas where three-phase power is required but space is limited. It is simpler than a set of three single-phase transformers, and has lower installation and operating costs and higher safety.
Product features
- Miniaturization: The three-phase pole-mounted transformer is compact in design and small in size, making it suitable for areas with limited installation space.
- Large capacity: For a given conductor size, a three-phase pole-mounted transformer can carry more power than a single-phase one.
- Low cost: Compared to connecting three single-phase pole-mounted transformers, a three-phase pole-mounted transformer reduces the cost of materials and installation
- Balanced load: A three-phase system naturally balances the load between phases, reducing the risk of imbalance that can lead to overheating and reduced efficiency.
- Low noise: Due to the symmetry of three-phase electricity, the transformer runs more smoothly with less noise and vibration

Features
1. Wound core with step-lap joints for increased efficiency and
lower noise levels.
2. Progressively wound coils with adhesive resins on insulating
paper or conductors for increased shortcircuit strength,
efficiency and thermal strength.
3. CSP protection package available as an option for increased
protection against surge currents, short circuits and overloads:
• Primary protective links
• Surge arresters
• Secondary circuit breaker
• Secondary breaker operating handle with emergency
overload reset and overload signal light.
4. Three point core-coil bracing for increased mechanical strength.
5. Self-venting and resealing cover that eliminates the need for
an auxiliary pressure relief device and offers increased safety
through higher tank withstand.
6. The paint finish process applies a durable, corrosion resistant
finish to the product. The finish meets or exceeds all the
performance requirements of ANSI C57.12.28. The multi-step
process includes an epoxy primer uniformly applied by cationic
electrodeposition and a urethane top coat.
7. Cover has 13 mils minimum of polyester coating providing
15 kV dielectric insulation of tank ground parts from live parts
and increasing resistance to corrosion. The cover is sloped 15
preventing water from collecting, thereby reducing the
chances of corrosion and leaking.
8. Tank bottom rim is three layers thick for increased durability
and resistance to shipping and handling damage.
