Resin Impregnated Generator Bushings

Trench & HSP generator bushings are a reliable solution when connecting generators or electric machines. The proven bushings are appropriate for indoor spaces and are resistant to generator cooling gases.

Bushings for generators or electric machines are suitable
for internal spaces and are resistant to generator cooling gases. They are available for two different types of cooling:

  • controlled air cooling from the machine side
  • natural cooling, controlled gas cooling or liquid cooling

Generator bushings

by Trench fulfill the highest requirements.

Type EMH

For controlled air cooling from the machine side oil-free generator bushing. Oil-free generator bushing with a solid active part made of resin-impregnated paper (RIP). The bushing has a condenser control and controlled air cooling from the machine side. The maximum allowable rated voltage is between 12 and 36 kV, and the maximum rated current is 36 kA.

Type VSH/VRH/VFH

For natural cooling, controlled gas cooling or liquid cooling.

Trench RIG Technology: Oil-free generator bushing. The active part consists of a solid core, made if fiberglass reinforced expoxy resin, impregnated under pressure
Available with porcelain insulator on the airside

The bushings are suitable for rated voltages of 12 kV to 36 kV and rated currents up to 50 kA.

Type EMI/EKMI

For natural cooling, controlled gas cooling or liquid cooling.

Oil-free generator bushings with a solid active part made of resin-impregnated paper (RIP) and a condenser control. We offer versions for natural cooling, controlled gas cooling, or liquid cooling. The bushings are suitable for rated voltages of 12 to 36 kV and rated currents up to 36 kA.
