Product Description
The structure of the SCTG33Y heavy-armored temperature-sensing optical cable
for pipeline leak monitoring is constructed by placing 250μm optical fibers into
a seamless stainless steel tube filled with a waterproof compound. The steel tube
is longitudinally wrapped with a stainless steel helical tape and a braided wire
mesh layer, followed by a double-layer fine round steel wire armor, and finally
extruded with a Polyethylene (PE) outer sheath.
Product Features
Fully Insulated & High Protection Structure Fully insulated design providing high
voltage resistance, anti-static discharge, flame retardance, explosion-proof
characteristics, and superior physical durability.
Multimode Fiber for Leak Detection Utilizes high-precision multimode optical fibers
specifically optimized for distributed temperature sensing and pipeline leakage detection applications.
Aging & Corrosion Resistant PE Sheath High-density Polyethylene (PE) outer sheath
delivers excellent antiaging, corrosion-resistant, and wear-resistant properties
in underground or harsh environments.
High Crush & Tensile Endurance Features extraordinary anti-crush and high-tensile
strength capabilities, enabling reliable deployment in heavy-pressure pipeline beds.
Triple-Layer Steel Armoring Protection Combines a stainless steel tube, helical
tape with wire braid, plus double-layer fine steel wire stranding for maximum mechanical defense.
Compact Design & Fast Thermal Response Compact outer diameter and streamlined
core structure ensure rapid heat penetration for quick, accurate temperature sensing and leak response.

Values are typical reference data taken from the official Huifiber datasheet. Confirm the final specification against the datasheet before ordering.
SCTG33Y is a heavy-duty stainless steel tube armored optical cable built for optical sensing in harsh and high-temperature environments.
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.
