RG10 coaxial cables are an essential component in many electronic systems and networking installations. They offer high signal integrity and low loss of transmission, making them ideal for long-distance signal transmission. With a durable and flexible design, RG10 coaxial cables are a reliable choice for both indoor and outdoor use.

Description automatically generatedRG-10/U Cable Structure

The RG-10/U is a 50-ohm double-shielded coaxial cable with an overall diameter of 0.463 inches and has a voltage rating of up to 4000 Vrms. It has an inner silver-plated bare copper conductor with 7-stranded construction (carrying the electrical signal), which is enclosed by an insulation layer typically made of solid Polyethylene (PE). The insulation layer is then completely enclosed by 2 silver-plated Copper braid shields that form an outer conductor and also provide a shield against electromagnetic interference (EMI). Finally, the structure is covered with an outermost layer called a jacket made of Polyvinyl Chloride (PVC). The jacket protects the cable core from mechanical, moisture, and chemical issues.

The RG-10/U cable exhibits capacitance of approximately 29.6 to 30 pF/ft, signal attenuation of around 6.0 dB/100 ft at 400 MHz (signal attenuation of the cable depends on the frequency) and has a velocity propagation of 67%. It has a center conductor measuring 0.0885 inches (2.25 mm) in diameter and an insulation layer measuring 0.285 inches (7.24 mm) in diameter.

RG-10A/U

The RG-10A/U is a 50-ohm coaxial cable with an overall diameter of 0.463 inches and has a voltage rating of up to 5000 Vrms. It has an inner bare copper conductor with 7-stranded construction (carrying the electrical signal), which is enclosed by an insulation layer typically made of solid Polyethylene (PE). The insulation layer is then completely enclosed with copper braid shield that forms an outer conductor and also provides a shield against electromagnetic interference (EMI).

It has a center conductor measuring 0.0854 inches (2.17 mm) in diameter and an insulation layer measuring 0.285 inches (7.24 mm) in diameter.
