WhatsApp Image 2025-04-01 at 21.21_edited.png

Advantages:

  • Easy access and maintenance

  • High insulation and mechanical strength against impacts

  • High internal insulation and high mechanical resistance against to shocks and sagging thanks to the use of large surface satiated bushings and M16 shear connectors

  • Special grid resistance design to prevent point overheating

​

Application Areas:

  • In power generators used in Power Generation Plants such as Thermal, Nuclear, Gas, Hydroelectric and Wind Power Plants

  • Step-up transformers used in Power Generation Plants such as Thermal, Nuclear, Gas, Hydroelectric and Wind Power Plants

  • In step-down transformers terminating energy transmission lines

  • Transformers and generators used in cogeneration and trigeneration systems in large facilities such as factories, hospitals, shopping centers

​

Specifications:

  • Suitable up to 110 /√3 kV

  • Applicable for fault currents up to 5000 A

  • Fault duration for 5 s, 10 s, continuous or other customer requirements

  • Stainless steel resistor material suitable for extreme ambient conditions, resistant to oxidation and corrosion (AISI304, AISI310, AISI316, AISI430, CrAl, CrNi)

  • Special mechanical and electrical design to withstand high temperature and extreme current values

  • Internal current transformer detecting failure current

  • Design and tests in accordance with ANSI-IEEE 32 standard and special specifications
