Jiangsu Elesun Cable Co., Ltd. is one of the leading manufacturers and suppliers of sywv50-7 foam pe insulation coaxial cable in China, also supports customized service. Should the bulk sywv50-7 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 engages in R&D and manufacturing of RF coaxial and special cables.
SYWV50‑7 Foam PE insulation coaxial cable 50Ω double shielded telecommunication feeder is developed matching Kansai 7D‑FB standard.
It uses foam PE as dielectric insulation material.
Characteristic impedance keeps 50Ω±2.
It delivers low loss, low delay and stable attenuation performance.
Standard jacket colors are black and white.PE, PVC, LSZH flame‑retardant jackets are selectable for different working conditions.
Raw materials comply with RoHS requirement.
Every batch passes factory inspection.
Internal Cable Construction
This RF coaxial cable adopts multi‑layer coaxial layout.
Bare copper works as inner conductor for good signal conduction.
Foam PE layer separates inner and outer conductors.
First shielding layer is aluminum tape against outside EMI interference.
Second shielding is tinned copper braid for enhanced shielding performance.
Outer jacket resists abrasion, moisture and environmental damage.
Double‑shield setup reduces signal leakage and outside noise intrusion.
Working Principle
SYWV50‑7 Foam PE insulation coaxial cable 7D‑FB equivalent low delay jumper cable transmits RF signals with coaxial physical structure.
Inner conductor carries RF electric signal.
Foam PE insulation maintains fixed conductor distance and cuts dielectric loss.
Double‑shield layers block electromagnetic noise and prevent signal distortion.
Electromagnetic wave propagates inside insulation space.
Controlled 50‑ohm impedance reduces signal reflection and SWR value.
Well‑matched structure ensures stable signal output under high‑frequency conditions.
