Insulation resistance assembly platinum resistance temperature insulation resistance shall be not less than 100MΩ; assembly thermal resistance of copper at room temperature insulation resistance shall not be less than 50MΩ temperature insulation resistance test voltage is 10 ~ 100V DC. Self-heating effects: platinum resistance allows the maximum current of 5mA corrosion by the thermal resistance selection, the resulting temperature of not more than 0.3 ℃. Nominal resistance: generally refers to the working temperature protection tube can withstand a static external pressure without breaking. RTD minimum insertion depth: not less than (except in exceptional circumstances) its protective casing diameter 8-10 times. When installing face thermal resistance due to its lead with a resistive element is connected, so to lead and face thermal resistance thermal resistance quote corrosion synchronous rotation, so as to ensure the face thermal resistance not be artificially damaged during installation, but the actual installation process inevitably happen. Because of this situation, the company increased research efforts Riko successfully developed a special face thermal resistance, which face thermal resistance when installing only need to unscrew the outer ends of the screws on it, do not need to lead and face thermal resistance synchronous rotation. Hot corrosion resistance Selection | Anhui Electric Group (certified) | corrosion thermal resistance provided by the Anhui Electric Group Co., Ltd .. Anhui Electric Group Co., Ltd. (www.ahecable.com) is Chuzhou, bare wires and bare conductor products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Anhui Electric Group leadership with the staff warmly welcome all inquiries negotiations to create Anhui Electric Group, a better future.
