Electrical Performance Of Bimetallic Terminal Blocks

2. Electrical properties mainly include contact resistance, insulation resistance, current and dielectric strength

① Contact resistance: High-quality electrical bimetallic lugs should have low and stable contact resistance. The contact resistance of bi metal cable lug ranges from a few milliohms to tens of milliohms.

② Insulation resistance: An indicator to measure the insulation performance between electrical bi metal lugs connectors contacts and between contacts and the shell, with an order of magnitude ranging from hundreds of megohms to thousands of megohms.

③ Dielectric strength or withstand voltage: Characterizes the ability of bi metallic cable lugs contacts or between contacts and the shell to withstand the rated test voltage, which depends on the gap between circuits (i.e., the contact spacing and creepage distance) and the insulating materials used in bimetal cable lug.

④ Current: Limited by the electrical bimetal terminal lug and its terminated wires.

Other electrical properties include electromagnetic interference leakage attenuation, which is used to evaluate the electromagnetic interference shielding effect of bimetallic lugs price, and is generally tested in the frequency range of 100MHz~10GHz.

For RF coaxial bimetallic lugs price list, there are also electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio (VSWR). Due to the development of digital technology, a new type of cable lug bimetal has emerged in order to connect and transmit high-speed digital pulse signals. Correspondingly, in terms of electrical performance, in addition to characteristic impedance, some new electrical indicators have also emerged, such as crosstalk, transmission delay, skew, etc.

3. Environmental performance

Common environmental performance includes temperature resistance, moisture resistance, salt spray corrosion resistance, etc.
