At present, there is no corresponding national standard definition for fireproof cables in the country. The cable industry is used to refer to cables with certain fireproof performance such as flame-retardant cables, fire-resistant cables, and mineral-insulated non-combustible cables as fire-resista...

XLPEDue to the above-mentioned twisted pair characteristics, when the microphone cable is welded with the corresponding Canon connector, the twisted pair will cross at 2.3 feet, which is easy to cause the plastic to melt during welding and cause a short circuit. Therefore, some manufacturers have in... READ MORE
The DC standard resistance of the cable can be calculated according to the following formula:R20=ρ20(1+K1)(1+K2)/∏/4×dn×10In the formula: R20——the branch current standard resistance of the cable at 20℃ (Ω/km)ρ20——The resistivity of the wire (at 20℃) (Ω*mm/km)d——diameter of each core wire (mm)n——the ...

3. DC resistanceThe DC loop resistance consumes part of the signal and converts it into heat. It refers to the sum of the resistance of a pair of wires. The DC resistance of the 11801 twisted pair must not be greater than 19.2 ohms. The difference between each pair should not be too large (less than... READ MORE
For twisted-pair cables, users are most concerned about several indicators that characterize its performance. These indicators include attenuation, near-end crosstalk, impedance characteristics, distributed capacitance, DC resistance, etc.1. AttenuationAttenuation is a measure of signal loss along t...
