Special Wire and Cable > Weather-Resistant Cable
Corrosion-Resistant Cable (Chemical/Sewage Area)
Engineered for signal transmission in the most demanding corrosive environments, this corrosion-resistant cable serves chemical plants, sewage treatment facilities, marine and offshore installations, and high-humidity industrial zones. Its rugged TPU jacket resists mineral oil lubricants, dilute acids, alkaline solutions, and other chemical media across a -45°C to +90°C operating range.
Key Features
Engineered for the Harshest Corrosive Environments
From high-salinity coastal zones to chemical processing plants, this cable is built to resist corrosion, abrasion, and electromagnetic interference in continuous signal transmission applications.
Superior Abrasion & Tensile Resistance
Withstands repeated flexing, tension, and mechanical wear in demanding control and signal transmission use.
Strong EMI Shielding
High-coverage tinned copper braid shielding (≥80%) resists strong electromagnetic interference.
Rugged TPU Chemical Resistance
Resists mineral-oil-based lubricants, dilute acids, alkaline solutions, and other chemical media.
Wide Operating Range
Rated from -45°C to +90°C, suitable for severe climate conditions.
Low-Friction, Non-Sticking Surface
The jacket surface does not adhere to other objects within the rated temperature range.
Compact Outer Diameter
A small cable outer diameter saves installation space while maintaining flame-retardant, UV-resistant performance.

Construction & Configuration
Multi-Layer Shielded Cable Structure
The cable pairs an extra-fine tinned copper conductor with a high-density insulation, TPU inner sheath, high-coverage shielding braid, and a rugged TPU outer jacket.
Extra-Fine Tinned Copper Conductor
Multi-strand extra-fine tinned copper wire per GB/T 3956-2008 Class 6 provides flexibility and current-carrying capacity.
High-Density Compound Insulation
A high-density insulation compound surrounds each conductor for reliable electrical performance.
Color/Number Core Identification
Cores below 0.5mm² use color or dot marking; larger cores use black with white numbering.
Tinned Copper Braid Shielding (≥80% Coverage)
A high-conductivity tinned copper braid with ≥80% coverage provides strong EMI shielding.
TPU Inner Sheath (High-Density Extrusion)
A high-density extruded TPU inner sheath adds a further layer of mechanical protection.
High-Performance TPU Outer Jacket
A high-mechanical-performance TPU compound outer jacket resists chemicals, abrasion, and mechanical stress.
