Oil-Immersed Series Transformer

The fully sealed oil-immersed power transformer, developed by Jinteng Electric, delivers exceptional performance with low loss, low noise, and high efficiency. Designed for energy-saving benefits and reduced environmental impact, it ensures reliable operation and minimal maintenance requirements. Its advanced sealed construction prevents air exposure, protecting the oil and insulation from degradation, thereby enhancing durability and performance.

Power Capacity: 30-5000KVA

Voltage Level: 10KV,1IKV,13.8KV,15KV,17.5KV,20KV,22KV,24KV,30KV,33KV,35KV,36KV...... 132kv and Others as customers requirement

Type of Voltage Regulation: Off-circuit or On-load

Tapping Range: ±5 %±2x2.5 %±4x2.5 %

Frequency: 50Hz or 60Hz

Phases: Three or single

Connection Symbol: Dyn11,Yyn0 ( or as requested)

Short-circuit lmpedance: Standard lmpedance

Altitude is not exceeding 1000m,ambient temperature not exceeding 400C

If it can't meet such conditions,we will modulate parameters in accordance with standard.

TRANSFORMER BODY

Transformer shell can withstand high temperature, good overloadability, impact resistance, and insulation. Reasonable arrangement of heat sink can dissipate heat faster.

TERMINAL

High quality terminal, with wiring instructions, easy to install.

PURE COPPER MATERIAL

Enhance mechanical properties, mechanical strength, dynamic stability, and thermal stability.

BUCHHOLZ RELAY

Buchholz relay (also called gas relay) is a protective device used in transformers. It is installed in the pipeline between the oil storage cabinet and the oil tank of the transformer. When the internal fault of the transformer causes the oil to decompose and produce gas or causes oil flow surge, the contacts of the gas relay will be activated, the specified control circuit will be connected, and a signal alarm will be issued in time or the protection element will be activated to automaticall
