High-frequency cable RG-213

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.

Cable Features

From its analogues, the RG-213 cable features an increased braiding density and the presence of a foamed dielectric coated with a layer of aluminum foil. It can work in the frequency range up to 4 GHz. Withstands a voltage of up to 5 thousand volts. The impedance is 50 ohms. The signal is transmitted at a rate of 66%, which corresponds to the deceleration signal.

It is suitable for use in territories with different 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.

Structure

RG-213 is a radio-frequency cable with twisted wires 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:

• Outer shell made of polyvinyl chloride.
• The protective shield is a braid made of tinned copper wire.
• Dielectric is a foamed polyethylene, which has a low density.
• The conductor is made of soft annealed electrolytic copper. It consists of a large number of veins intertwined.

The outer diameter of the cable is 10.3 mm. The outer shell to which the cable is coated 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.

Application area

As already mentioned, the RG-213 cable is a high-frequency cable. 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 the signal for long distances without losing it and significant changes.

A cable is suitable for transmission of high-frequency signals in electronic devices (computers, television transmitters, radio tape recorders, transmitters, etc.). It 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.
