Porcelain Insulators IOS-35-1000 UHL1 by VOLTA

Purpose:
The IOS-35-1000 UHL1 insulators by VOLTA are designed for the insulated attachment of live electrical components within complete distribution systems, open electrical stations, and substations operating at alternating voltages over 1000 V and frequencies up to 100 Hz. These insulators are recommended for use in regions with harsh climates, where high atmospheric pollution, icing, and frequent fog are common.

Key Advantages:

  • High mechanical bending strength.
  • Verified torsional strength through testing.
  • Compatibility with disconnect switches.
  • Excellent pollution resistance, ideal for challenging environmental conditions.
  • Outstanding electrical properties validated by high-voltage tests.
  • Slow aging rate, ensuring long-term reliability.
  • Reduced weight, facilitating installation, reducing structural metal demand, and simplifying transportation logistics.

Warranty:
The warranty period for the insulator is 10 years from commissioning. Its total service life is at least 35 years. The manufacturer provides free replacement for damaged insulators within the warranty, assuming no installation or operational violations are detected.
