For the transmission of high frequency signals, the coaxial cable RG-213 is used. It has improved performance compared to its predecessor RG-8 / U.
From its analogues, the RG-213 cable is differentincreased density of the braid and the presence of a foamed dielectric coated with a layer of aluminum foil. It is able to operate in the frequency range up to 4 gigahertz. Withstands voltage up to 5 thousand volts. The impedance is 50 Ω. The signal is transmitted at a rate of 66%, which corresponds to the deceleration signal.
It is suitable for use in territories withdifferent climatic conditions. He copes with his functions in the temperature range from minus 20 to plus 80 degrees. This means that it can be used practically throughout the entire territory of our country.
RG-213 is a radio frequency cablewith twisted strands and braid. And the latter is done only from copper. Its structure is a multicore conductor around which an insulating screen is located.
The cable consists of the following parts:
The outer diameter of the cable is 10.3 mm.The outer shell, which is covered with a cable, has a thickness of 1.1 millimeters. Almost 98% of it is covered with a protective screen with a layer thickness of 0.18 mm. Located inside the dielectric in diameter is 7.24 millimeters. The conductor consists of 7 interconnected veins, each of which in diameter reaches 0.75 millimeters.
As already mentioned, the RG-213 cable ishigh-frequency. This means that it is used to transmit signals with a high frequency. It can be used under various temperature conditions, both inside and outside the premises. Due to its characteristics, the cable can transmit a signal for long distances without losing it and significant changes.
A cable is suitable for transferring high-frequencysignals in electronic devices (computers, television transmitters, radio tape recorders, transmitters and so on). Can also be used to transmit radio signals in video surveillance systems, communication systems.
In addition, the cable is suitable for use as delay lines, in transformers of various types, pulse filters and shapers, matching devices.
The cable is transported in coils of two kinds.In the first case, the cable length in it is 100 meters. The coil has an external diameter of 36.5 centimeters. Its height is 10 centimeters. The total weight of the cable in the coil reaches 12 kilograms. The weight of the coil of the second type is 35 kilograms. The RG-213 cable in this case has a length of 305 meters. The outer diameter of the coil is 35.5 centimeters. Its height is 35 centimeters. In both cases, the cable is pulled with cellophane and packed in a box.
