        Project Introduction

        Insulation is a safety measure that uses a non-conductive substance to isolate or wrap the charged body to protect against electric shock. Simply put, the size of the insulation resistance of electrical equipment is the ability to isolate voltage. Insulation test is a test to check the dielectric strength of insulating materials or the insulating structure of electrical equipment. The purpose is to check the safe operation of products and equipment, to prevent short circuits and dangerous accidents.

        Scope of application

        Applicable objects of insulation test

        Electrical equipment, electrical components, insulating materials

        Test Methods

        Under normal circumstances, the insulation resistance test is to output a fixed value of DC voltage value, and then detect the leakage current to ground or other parts. After pressurizing it for 1min, the degree obtained is the insulation resistance value. In the insulation resistance test, the most important part is the absorption ratio test, which can reflect the degree of insulator damage and moisture regain in electrical equipment in time. Normally, the insulation resistance of the equipment at room temperature is qualified and the absorption ratio is within 1.3 before the insulation of the task equipment can be qualified.

        Importance of insulation testing

        During the operation of electrical equipment, it is always under the influence of various external factors, and its performance will continue to change. These external factors include external electric fields, environment, high voltage, corrosion, and machinery. Under the influence of factors, unpredictable failures are more likely to occur, and serious power interruption will also occur. Therefore, the insulation test of the high-voltage electrical equipment in the power system should be conducted before it is put into operation to ensure the safe and stable operation of the power system. Therefore, in order to ensure good insulation of high-voltage electrical equipment and stable and safe operation of power systems, it is necessary to conduct insulation tests on electrical equipment.

        • Network Camera SRRC Certification

          Network Camera SRRC Certification

          SRRC certification is one of the necessary conditions for products to enter the Chinese market for sale. It ensures that the wireless transmission characteristics of the wireless camera comply with national standards, avoiding communication problems caused by radio interference and ensuring the legality and compliance of the product.

        • Wireless microphone FCC ID certification

          Wireless microphone FCC ID certification

          FCC certification is a mandatory requirement for wireless device certification in the US market. Through FCC ID certification, wireless microphones can prove their compliance with US radio transmission standards, avoiding market bans or fines for violations. This is particularly important for products that hope to be sold in the US market.

        • Intelligent door lock KC certification

          Intelligent door lock KC certification

          KC certification ensures that products comply with relevant laws, regulations, and safety standards in South Korea, and is a necessary condition for smart door lock products to enter the South Korean market. KC certification covers wireless radio frequency, electromagnetic compatibility, and electromagnetic exposure. Strict testing and evaluation are required to obtain KC certification before products can be legally sold in the Korean market and gain consumer trust.
