High Voltage Insulators

Customised Cast-Resin High Voltage Insulators

High-voltage insulators and bushings made to order in cast resin.

Radiant is a well-known manufacturer of custom epoxy terminals for a variety of transformer and transducer uses.

For bushings and epoxy terminals used in high-stress, high-voltage applications, Radiant has significant expertise casting tailored insulating parts in epoxy that meet or exceed all quality, durability, and efficiency criteria.

Radiant's measuring and inspection systems are all designed to provide a thorough product evaluation, which is especially important when working with bespoke high voltage insulators. In addition to the necessary product knowledge, we create specialist resin formulas to achieve the best possible relationship between the product's various technical characteristics and specific customer requirements, such as rupture resistance, temperature stability, application temperature, mechanical strain, and so on. When it comes to energy transmission, this means that the required safety and durability criteria are met.

In partnership with partners, Radiant also provides white insulators made from aluminium oxide filled polymers for SF6 high-voltage switchgear.

Current Transformer Base

An electrical insulator is nothing but a substance that prevents electric current from flowing freely. Other materials conduct electricity more easily, such as semiconductors and conductors. Insulators differ from semiconductors and conductors by their resistivity; insulators have higher resistivity than semiconductors or conductors. The most common examples are nonmetals.

There is no such thing as a perfect insulator since even insulators contain a tiny number of mobile charges that can conduct current. Furthermore, when a sufficiently high voltage is supplied, the electric field pulls electrons away from the atoms, all insulators become electrically conductive. This is known as an insulator's breakdown voltage. Materials with higher resistivity like paper, glass and PTFE are excellent electrical insulators. Even though they have lower bulk resistivity, a far larger class of materials are good enough to prevent considerable current from flowing at regularly used voltages, and hence are utilised as insulation for electrical wiring and cables. Rubber-like polymers and most plastics, which can be thermoset or thermoplastic in nature, are examples.

Insulation is nothing but a mass insulating substance used to wrap electrical lines and other equipment. Insulators are also the insulating supports that connect distribution and transmission wires to utility poles and transmission towers in the electric power industry.

We offer lasers, power tubes, and high voltage bushings in a variety of designs, as well as precision-made high voltage insulators for use in analytical applications.

The line comprises vacuum-compatible designs and components capable of insulating against extremely high voltages, corrosive atmospheres, and intense thermal shock for extremely demanding applications.

Our high voltage insulators can also be used for precise machining, brazing, and metallization.

We are able to provide reliable and robust product solutions to some of the most difficult power production requirements because we are a global leader in applications engineering. We collaborate with customers from the start to identify the most practical and cost-effective solution.

Our vertically integrated production facilities provide us with complete control over the manufacturing process, from product design to final testing.
