Application

Ouwei electric is the leading provider of electrical insulation material ,Magnet wires, Foil conductors , bushing and Component Parts products used to manufacture and repair electric transformers . From core and barrier insulation to layer and magnet wire insulation and so on, Ouwei electric offers more than 20 years of experience in a variety of applications

Magnet wire

Copper or aluminum wire that makes up the transformer coil. The choice of magnet wire and lead wire depends on a number of factors, including the necessary dielectric strength and temperature resistance, the transformer’s environment, and the size needed to carry the amount of electrical current required by the application. Ouwei sells a full line of magnet wire in all insulations, shapes, and sizes.

Electrical sleeving and tubing

Provides insulation for electrical connections and additional protection to critical areas where conductors can experience mechanical or electrical stress. ouwei offers a full line of electrical sleeving and tubing from industry leading manufacturers in bulk packaging and cut-to-length pieces.

Core insulation

The primary insulating material between transformer coils and the magnetic steel, core insulation is made of relatively thick insulating films, papers, or laminates. Ouwei electric slits these materials to specified dimensions and can also provide product in sheet form.

Lead pads

Made of pressure-sensitive tapes, flexible films, papers, and laminates, these pads serve as additional electrical insulation for the lead and tap connections. Ouwei electric provides material for lead pads as sheets, slit rolls, and fabricated parts.

Layer insulation

This insulation is placed between individual conductor windings in transformers.
Ouwei provides slit rolls in specific lengths and sheets from many different flexible insulating films, papers, and laminates.

Barrier insulation

The primary insulating material between high- and low-voltage coils, barrier insulation is made of various flexible films, papers, and laminates. Oukepu converts these materials into sheets, slit rolls, and fabricated parts.

Magnet wire insulation

Paper wrapped magnet wire conductor is used in certain types of transformers. Ouwei electric provides slit rolls of various insulating papers in traverse-wound spools suitable for wire wrapping equipment.

Pressure-sensitive tapes

In transformer manufacturing, these tapes are used to hold components in place during the manufacturing process, as well as to provide additional electrical insulation. Ouwei electric slits a wide variety of pressure-sensitive tapes to customer-specified widths and also provides custom diepunched parts for discreet applications.
Ouwei electric offers a variety of other transformer components,including:

Foil conductors

Copper and aluminum foils are used as conductors in transformer coils, as well as EMI/RFI and electrostatic shields. Ouwei electric manufactures custom shields using a variety of insulating tapes, films, and papers to customer specifications. Ouwei electric sells custom slit foil conductors from several industry-recognized sources.

Duct spacers

These components are solid rods or bars used as spacers between transformer windings in order to allow cooling air or liquid to flow through the transformer. Duct spacers are made of rigid electrical insulating materials, such as thermoset polyesterglass composites. Ouwei electric sells duct spacers in several shapes and sizes supplied in bulk lengths or cut to specified lengths.

Woven cloth tapes

ouwei electric supplies many types of coated and non-coated woven cloth tapes used in a variety of holding, insulating, and overwrapping applications in transformer coils.Non-coated woven tapes readily absorb varnish, which helps create a rigid coil structure. Coated cloth tapes are used as both primary and secondary insulation, and are available in a wide variety of constructions.

Transformer bushing insulators

Transformer bushing insulators are applied as a structure, carrying on conductor through a partition such as transformer tank and insulating it, incorporating the means of attached flange to the partition for medium voltage level.
For Entire Range of Bushings Ratings from – 1 Kv to 72 Kv & – 100 Amp. to 10,000 Amp.
All Ares Insulator transformer bushing insulators are made of ceramic materials according to IEC 672. Other Transformer bushing custom-made insulators can be supplied upon customer’s request and specifications.
