Transformers are key parts of the way we get our power. In a power distribution network, transformers manage inconsistent loads and potential faults in an array of other units. The operating voltage of transformers increases as the level of power running through them increases. As a result, many power manufacturers are choosing silicone transformer liquids, in place of cast resin transformers due to their many benefits.

In general, liquid-filled transformers provide higher reliability and longevity, particularly in mechanically stressed environments.

Xiameter is a high-performance brand providing silicone rubbers, lubricants, silicone fluids and emulsions, defoamers, silanes and silicone moulds for industrial applications.

Xiameter PMX-561 Silicone Transformer Liquid is the Silicone Solution for the Energy Industry

Silicone liquids, such as Xiameter PMX-561 (previously known as Dow Corning 561 Silicone Transformer Liquid.), provide superb performance in liquid transformers where fire safety and thermal stability are of importance.

PMX-561 Silicone Transformer Liquid for energy industry

Xiameter PMX-561 is a silicone transformer liquid designed for transformers and electrical equipment, including high voltage switches and circuit breakers. It is used as a cooling and insulating fluid. The polydimethylsiloxane liquid is compatible with a range of solid electrical insulating materials. Additionally, it contains no additives such as thermal stabilisers.

Xiameter PMX-561 is capable of reducing fire risk through having a higher fire point and lower heat release rate than most other insulating liquids. Additionally, it has a low viscosity (50 centistokes) with good electrical properties and operating capabilities over a wide range of temperatures.

Indoor transformers, or those near to buildings, can benefit especially from Xiameter PMX-561 due to its high thermal stability and oxidation resistance; reducing power outages while extending the transformer service life.

PMX-561 Silicone Transformer Liquid for the wind industry

Xiameter PMX-561 Silicone Transformer Liquid is an environmentally safer alternative to minderal transformer oils, due to being non-toxic, non-halogenated and non-hazardous.

Railway and wind industries, as well as oil and gas manufacturing facilities, benefit from a transformer liquid such as this since fire safety is a critical factor to overall operations.

Xiameter PMX-561 meets the requirements of IEC 60836 and ASTM D 4652-92 for use in electrical transformers. These standards cover the physical and electrical properties of fluids suitable for dielectric applications.

Xiameter PMX-561 Key Benefits

  • Highly stable over a wide temperature range
  • Resistant to oxidation
  • Great electrical properties
  • Environmentally friendly – no additives, non-halogenated, non-hazardous
  • Low heat release rate
  • High fire point
  • Great compatibility with electrically insulating materials
