20 Jan In Focus – Electrical Insulation
Textile fibres for the electrical and electronics industries were the backbone around which Multiple Winding was born, and they still play an important part in the markets we serve. Composite yarns (or daglass – dacron-glass – as they are sometime known) are a combination of lightweight glass and polyester yarns, and are used extensively to wrap copper components in turbines, generators and HVAC equipment, the glass forming an insulating layer and the polyester often being fused around it as a resin matrix.
Composite fibres from Multiple Winding come in a range of tex counts, and either as a ‘singles’ yarn (one pair of combined polyester glass yarns), or they can be multi-end wound in a variety of different package structures and end counts, up to a maximum of 45 ends.
We can also multi-end wind singles glass yarns, common tex counts including EC5 2.8, EC5 5.5 and EC5 11, again up to 45 ends, which are also used as copper wraps, but are also used in thermocouple manufacturing markets as an insulating coating, often fixed with a resin.
Other higher texes are also available in this field, along with S-glass materials for higher temperature resistance. Whatever your needs, Multiple Winding can help!!
