Published: 2026-06-30

Shanghai Suoqi Cable Co., Ltd. focuses on the special flexible cable field. The following provides a professional interpretation of encoder cables from three dimensions: material structure, performance advantages, and application scenarios.

Product original text reference: High-flexibility oil-resistant servo cable

1. Materials and Structural Parameters

Uses annealed oxygen-free copper wires with a purity of up to 99.9999%, ensuring low resistance and high conductivity, while the multi-strand fine wire twisted structure provides excellent flexibility, suitable for frequent movement.

Cable shielding layer is designed with aluminum foil Mylar/tinned copper wire mesh, and the power-type structure can be designed with single or double overall shielding.

The cable adopts a special high-flexibility structure design, optimizing the cable conductor and core wire twisted structure, particularly suitable for frequent reciprocating bending movements in servo drag chain systems, and can also be used for fixed installation in servo motor systems.

It also has properties such as acid and alkali resistance, waterproof, UV resistance, sunlight aging resistance, crack resistance, mechanical fatigue resistance, heat resistance, and flame retardancy, capable of adapting to various complex industrial environments.

2. Performance Technical Indicators

The highly flexible oil-resistant servo cable produced by Shanghai Suoqi is one of its featured products, specifically designed for servo motor systems, with excellent performance such as high flexibility, oil resistance, and anti-interference. The following is a detailed introduction:

Uses specially modified PVC compound or TPEE materials, which have good insulation performance and mechanical strength, effectively preventing signal interference, while also being oil-resistant and chemically resistant.

The outer sheath is made of special modified elastomer material or high-quality polyurethane (PUR) material, providing excellent wear resistance, oil resistance, tear resistance, and weatherability, and color can be customized according to customer requirements.

The high-density shielding mesh layer effectively isolates external electromagnetic interference, ensuring the accuracy and stability of signal transmission, thereby guaranteeing the reliable operation of the servo system.

3. Application Scenarios

The choice of protective layer material that fits the operating conditions allows it to meet servo connection installation applications in light or heavy oil contamination environments and can withstand various oils such as mineral oil and lubricating oil.

Suitable for dry or damp indoor environments, as well as occasional bending and moving situations in industrial use, such as machine tools, woodworking machinery, and grinding machines. It is also widely used in industrial machinery and equipment, transmission and conveyor control systems, various industrial sensors, testing instruments, and other equipment, and can be used for power and signal connections in harsh environments and oil-resistant conditions.
