Jiangsu Elesun Cable Co., Ltd. is one of the leading manufacturers and suppliers of sywv50-3 foam pe insulation coaxial cable in China, also supports customized service. Should the bulk sywv50-3 foam pe insulation coaxial cable made in China caters to your requirement, welcome to get the datasheet from our factory.
Product Overview
Jiangsu Elesun Cable focuses on R&D and production of RF coaxial and special cables.
SYWV50‑3 Foam PE insulation coaxial cable 50Ω double‑shielded miniature antenna feeder is manufactured to match Kansai 3D‑FB standard.
It adopts foam PE as dielectric insulation material.
Characteristic impedance keeps stable at 50Ω±2.
This cable features compact and lightweight dimension, low loss, low delay and minor attenuation.
Standard jacket colors include black and white.PE, PVC, LSZH and FR‑LSZH jacket materials are available.
Raw materials comply with RoHS.
Every batch passes incoming and outgoing inspection.
Cable Construction
This miniature RF coaxial cable adopts multi‑layer composite coaxial layout.
Bare copper works as inner conductor for stable electrical conduction.
Foam PE insulation separates inner conductor from shielding layers.
First shielding layer is aluminum tape to block external electromagnetic interference.
Second shielding is tinned copper braid to improve overall shielding performance.
Outer jacket resists abrasion, moisture and environmental damage.
Double‑shield setup reduces signal leakage and outside noise intrusion.
Working Principle
SYWV50‑3 Foam PE insulation coaxial cable 3D‑FB equivalent low‑delay RF jumper wire transmits RF signals by coaxial physical structure.
Inner conductor carries RF electric signal.
Foam‑PE dielectric keeps fixed conductor distance and cuts dielectric loss.
Double‑shield layers isolate electromagnetic noise and prevent signal distortion.
Electromagnetic wave propagates inside foam‑PE dielectric space.
Controlled 50‑ohm impedance reduces signal reflection and SWR value.
Well‑matched structure guarantees stable signal transmission under high‑frequency working conditions.
