TECHNICAL INFORMATION

PRODUCT ADVANTAGES

Air is a near perfect dielectric medium allowing

a signal to propagate through it at approximately

NEWcel^® is the perfect solution. A closed-cell

foamed dielectric material specifically designed

to reduce dielectric constant and dissipation

factor yielding low-capacitance, low-loss, high

V.O.P. ultraminiature coaxial, triaxial and

twinaxial cables.

Typical coaxial, triaxial and twinaxial cables

are manufactured using low dielectric constant

(2.0 - 2.6) materials that possess inherently

better electrical properties than standard

insulation material such as PVC. Using highly

controlled extrusion processes, these materials

are foamed yielding a dielectric medium with a

high air concentration. The result of this process

is a significantly reduced dielectric constant

(1.45 - 1.8) that approaches the nearly ideal

properties of air without sacrificing structural

integrity. This results in a significant capacitance

reduction while providing the customer with the

choice of reduced diameter/same attenuation or

same diameter/reduced attenuation.
