Looking for Just provide a few details and we will help you get quick quotes! If you pour water all over a spool of bare copper without insulation the copper will get corroded and less affective, or completely defective, when connected in an application.

There are various types and levels of insulation protection to resist water, oil, solvents, gas, chemicals, weather, rodents, terrain and even certain levels of impact resistance. These things need to be discussed with the customer to determine which items need resistance in their particular application in order to find the accurate wire to support their needs.

For example, oil and grease are used to provide maintenance and could come in contact with the wire, so the insulation needs to resist both. Some transformers are powered by gas so the wire may or may not need gas resistance. All of these types of liquids need to be discussed and considered when finding the right type of insulation for the wire or cable. Transformers can use either copper or aluminum wire, but more often use copper.

Magnet wire is used in the coils while insulated wire is used for connections. The insulated wire is also coated with a varnish or enamel in air cooled transformers to prevent the conductors from shorting together. After reviewing the insulation, temperature and voltage requirements, the engineers can put together the harness drawing knowing that the wires will last in the particular type of transformer.

Now they will be busy working on the exact dimensions, connectors, housing, labels, tubing and sleeving products that accompany the full wire harness. In a perfect world the customer will receive the harness and plug it into their transformer without having to complete any additional work.

Nor should they have to conduct tests for voltage and temperature to see if it can withstand the approvals they requested because it will have already been tested by the manufacturer of the wire, along with a third party UL.

Transformers use copper instead of aluminum for electrical conductivity and for size. Copper is heavier but less is needed for the same approvals of electrical current and testing, meaning the overall unit size is smaller when using the more expensive copper. Certified as reinforced insulation; three layers can resist up to 3, ACV for one minute. Please refer to the list of Safety Standard about the details. A lot of insulation systems by UL are provided. Please refer to item of " UL; insulation system " in the page of acquisition status of overseas safety standards.
