Why you should choose a microwave cable assembly?

There are many technical reasons why you should choose a microwave cable assembly. However, the cable’s electrical performance, environmental characteristics, and mechanical performance determine this. In some environs, the cable’s fire performance also comes in handy. These features are all related to the material and structure of a microwave cable assembly.

What’s the main function and features of a microwave cable assembly?

The microwave cable assembly’s main function is transmitting signals. This means the materials and structure of the cable have to ensure a steady transmission characteristic throughout its lifespan. With this let dig deeper into the features of the cable.

  1. Inner Conductor

The cable’s inner conductor is mainly copper. The copper can either be annealed copper tube, copper-clad aluminum wire, or annealed copper wire. Overall, the cable’s inner conductor is copper wire. However, larger cable assemblies use copper tubes to cut down the cost and weight of the RF cable.

  1. Outer Conductor

The outer conductor serves two main purposes: a circuit conductor and a shield. The microwave cable assembly outer conductor also helps in determining leakage performance. The outer conductor of a microwave coaxial cable assembly must also be completely closed to eliminate the possibility of radiation.

  1. Insulating Medium

Microwave coaxial cables dielectric offers more than just insulation services. Its final transmission enactment is mostly determined after the insulation. It’s therefore important to be keen on the selection of materials and the cable structure. Every important property, like attenuation, return loss, and impedance, is related to insulation.

Unique multi-layer insulation coextrusion procedure will obtain a closed and uniform foaming structure – A reason for the cable’s stable mechanical property, moisture resistance, and high strength characteristics.

To maintain better electrical performance within humid environs, you can get a customized coaxial microwave wiring harness that features thin, solid-core PE within its outer foam insulation surface. The thin outer layer will effectively counter moisture intrusion while still protecting the electrical capabilities of the microwave wiring harness.

  1. Sheath 

A black UV-resistant HDPE helps the cable withstand different climatic stresses in that area caused by strong UV and extremely high temperatures. For fire safety, then it’s important to use halogen-free low smoke flame retardant materials. You can also use flame retardant and fireproof tape between the sheath and outer conductor. This helps in keeping the easy-melted insulating layer in its best condition.

Is microwave coaxial harness widely used?

Microwave coaxial wiring harness features lots of applications. It’s for this reason that many industries are making use of them. However, always ensure you choose a microwave oven wiring harness that best suits your needs.
