Combined Transformer
Product Details
OIL-PAPER INSULATION: Wide range of primary currents: from 1 to 5000 A. Oil level compensating system that eff ectively regulates changes in oil volume mainly caused by temperature. Oil sampling valve for periodic analysis. The materials used for construction are recyclable and resistant to the elements. Its advanced design adheres to environmental regulations through the use of high quality insulating oils, free of PCB.
GAS INSULATION:
› Total safety in case of internal arc: overpressure is relieved by the pressure relief device (rupture disc) in the top part of the head.
› The silicone rubber insulator guarantees safety during transportation and service.
› Online monitoring of the insulation status with a manometer alarm.
› Compact and very light design.
› Designed to minimize gas volume, pressure and leaks, thus reducing its environmental impact.
DRY INSULATION:
› Cast in high dielectric strength resin.
› Primary winding with spark gap for over voltage protection.
› Compact design for easy handling.
› May be transported, stored and installed vertically or horizontally.
› Porcelain or silicone rubber insulators.
Top-core Type:
› All types of measurement and protection cores: multi-ratio, linear…
› Very high rated currents and short-circuit currents.
› Reinforced safety design, resistant to internal arc.
› Metallic oil bellows and tangent delta measurement tap.
Hairpin Type:
› Excellent seismic performance.
› Good heat dissipation in the primary conductor.
› Reduced size makes it extremely easy to handle.
› Option for metallic oil bellows and tangent delta measurement tap.
ESGCC GLOBAL uses blockchain technology to record complete and trusted transaction information to prevent information loss and data tampering. It can share information between various transaction subjects, reduces communication costs caused by information asymmetry, and enables the entities on the chain to operate collaboratively under the unified consensus mechanism of the blockchain.
