Insulation system is a close combination of two or more insulating materials used in electrical equipment. Insulating materials generally include enameled wire, skeleton, tape, lead, sleeve, vanity water, cable tie, etc. Insulating materials are used There are a lot of products, including motors, transformers, inductors, etc. or products containing these components, such as power supplies, pumps, LED lights. It should be said that most electrical products can see insulating materials, so it is very likely When applying for UL certification, you need to consider the issue of UL certification for insulation systems.

UL insulation system grades are divided into: Class E 120°C, Class B 130°C, Class F 155°C, Class H 180°C, Class N 200°C, Class R 220°C, Class S 240°C, etc. Each temperature class of the insulation system must be strictly tested to determine the thermal aging required by the standard UL1446. Testing not only considers the performance of a single material, but also takes into account the compatibility or matching of the entire system material. Therefore, the UL system will add multiple types and specifications of materials that are tested or evaluated one by one. The system has also been established.

The product category number (CCN) of the insulation system UL certification is OBJS2. UL puts various insulating materials at the same temperature for aging, and the aging time is generally longer to determine whether these materials can be used compatible. When companies that produce motors or transformers apply for UL certification, when the product uses insulating materials with a temperature higher than 105C or when the ambient temperature used has higher requirements, it needs to copy the UL insulation system (OBJY2). The insulation system copy is not Need to provide samples for testing, but to verify whether the insulation material used in the product matches a certain mother insulation system. The company first needs to provide a list of insulation materials for the product, including the material name, brand number, corresponding rated parameters and UL file number. If necessary, the company needs to obtain an authorization letter from the parent system company, agreeing to authorize this insulation system to be copied and used by the company. After UL received the above information, it started the project and completed the file creation. After copying the insulation system, the company should send samples of motors or transformers using the specified insulation materials to UL for the next electrical test.
