The GYFTY83 cable uses physical and chemical design against rodents, ants and birds: 250 µm fibers sit in PBT loose tubes filled with fiber gel, stranded around a non-metallic central strength member with water-blocking gel in the interstices.
An inner sheath, a non-metallic FRP armour layer and aramid yarn follow, then the outer sheath. Because every element is dielectric, the cable is ideal for lightning-prone routes and for power-corridor installations where metal armor is not allowed.
GYFTY83 is the armored, bird-proof sibling of the standard GYFTY non-metallic stranded cable: same stranded core, plus an FRP armour layer for anti-rodent, ant and bird performance. Span-specific tension data is designed per route, following the IEEE 1222 and IEC 60794-1 framework; on this page the PE/AT sheath split follows the catalog.
Product Features
Non-metallic armour — FRP armor layer resists rodents, ants and birds without any metal in the cable.
Aramid yarn — enhances tensile performance and reduces ice and wind loads on towers and supports.
All-dielectric build — no grounding needed; ideal for lightning-prone areas and power corridors.
AT sheath option — tracking-resistant sheath for lines above 110 kV (span-dependent design).
Light weight, small diameter — reduces tower and support loading versus metal-armored builds.
Fiber protection — PBT tubes filled with fiber gel cushion the fibers through installation and service.
Typical Applications
Power-corridor overhead routes where rodents, ants and birds threaten standard ADSS; lightning-prone regions where no metal can enter the span; lines above 110 kV that need a tracking-resistant AT sheath; and tower routes where the aramid-reinforced build keeps ice and wind loads low.
Selection and ordering
Order by span length, climate class and line voltage: the RTS, MADT and sheath (PE or AT) are engineered per route under IEEE 1222. Send the span, weather zone and voltage for a matched span sheet and quotation.
Packaging, delivery and support
Cables are supplied on standard wooden reels (2530, 4056 or 610 types) with embossed meter marks every meter and desiccant-packed ends; GYFTY83 reel lengths follow the quotation and can be split to match splice-point spacing. Every reel ships with a factory test report covering attenuation, OTDR traces and geometric checks. As a Dongguan factory with 20,000+ m2 of production space we support OEM and ODM branding, neutral packaging, third-party inspection before loading, and consolidation with the patch cords, splitters and ODF hardware on this site in one container. Sample lengths are available for qualification, and our engineers review pulling plans, splice schedules and closure layouts free of charge before dispatch. Typical lead time is two to three weeks for standard builds and four to five weeks for span-engineered or OEM-branded orders, with photos and loading records sent before every container leaves the factory.

Yes. Huifiber supplies cable under the buyer's own brand as well as under the Huifiber brand. Fibre count, jacket material, jacket print, drum marking, drum length, packaging and datasheet layout can all be produced to the customer's requirement, and the engineering team can work from a customer specification or adapt an existing construction to a new route requirement.
Every production batch is tested before it leaves the plant in Dongguan. Attenuation and geometry are measured on OTDR and optical bench equipment, and mechanical performance is verified against the datasheet for the construction. A factory test report is issued with each shipment, so an incoming inspection can be checked against the same numbers.
Send the fibre count and fibre type, the jacket material or fire rating, the route length or span and the drum length you need, the destination port or country, and any certification or test-report requirement. With those details the sales engineer can confirm the construction and return a quotation with an indicative lead time.
