UL1446 Insulation system certification, insulation system UL1446 certification (OBJY2), transformer insulation system OBJY2 certification

Do you want to pass the UL1446 insulation system certification easily and smoothly? Dongguan Xingyuan Electronic Technology Service Technology Co., LTD Specialized in UL1446 insulation system certification, insulation system UL1446 certification (OBJY2), Transformer insulation system OBJY2 certification. (Electrical Insulation System, Referred to as EIS) is a variety of insulation materials with each other to achieve a certain temperature resistance level of the material assembly, such as Wire, Bobbin,Tape,Varnish together to form a GROUP, and this group if approved by UL 1446, it becomes an effective insulation system. We can help you get the UL certificate in one go.

UL1446 Standard for Systems of Insulating Materials – General

Composition of insulation system ----

A.Major components- insulation systems rely on these components to protect against electric shock or fire, such as :wire,ground insulation, interwinding insulation, encapsulant.

B. Moor components- Insulation systems do not rely on this component to prevent electric shock or fire, but use the mechanical or thermal conductivity of this component. This component includes bobbin(not as ground insulation)varnish(not declared as main insulation),margin tape, cross-line fixed tape, interlayer tape, sleeve,pvc lead,window insulation(with ground or dead metal distance more than 0.8mm)

Each temperature class of the insulation system is rigorously tested to determine the thermal aging required by standard UL1446. Testing is not only for the performance of individual materials, but also to fully consider the compatibility or matching of the entire system material. Therefore, multiple types and specifications of materials tested or evaluated to be qualified are added to the system one by one, and the system is built from this. For example, the main insulation tape, contains multiple tape suppliers, such as 3M, and each supplier's multiple specifications of products will be listed, other such as skeleton materials, casing, water, etc.

1. All winding products are certified together in a short time, eliminating the trouble of single product inspection and reducing costs

2. Products can be affixed with UL mark, improve the company image and product quality, to meet the needs of customers

3. Wide source of materials, low cost. Such as: Changchun Bakeries T-373J, 3M tape 1350, Lanling Teflon casing, unlimited brand leadout, four-dimensional tape MY9 and DuPont Nomex, Nylon, PBT, etc.

4. Low temperature materials are used in high temperature systems to reduce material procurement costs

5. The use of solvent-free Fanliwater, reduce environmental pollution, to solve the danger of flammable products and finished product noise heat dissipation temperature rise and other problems

6. Various temperature and voltage ranges can be selected, such as: low voltage 600V, high voltage 34.5KV and 130~240 ℃
