Drag chain cable/servo cable/encoder cable:

Super-flexible drag chain cable is suitable for mobile use and has a bending life of 10 million times. It can be adapted to Siemens, Beifu, Rexroth, Schneider, Luster and other European motors. Provide Intercontec Intecon connector and its cable assembly.

Radiation-resistant flexible drag chain cable (model: YJRT-Flex):

When "harshness" becomes the standard in the nuclear power industry, safety becomes a crucial factor. In the face of extreme levels of radiation, pressure and temperature, in these dangerous environments, reliability, safety and long service life are the basic characteristics of cables. Our cable and harness solutions are designed to meet various safety requirements and adapt to harsh working environments, such as radiation resistance, oil resistance, chemical resistance, UV resistance, etc.

The drag chain cable is a kind of wear-resistant, oil-resistant and highly flexible special cable, which is suitable for occasions when the equipment unit needs to move back and forth. Drag chain cable is suitable for equipment connection line, equipment often repeatedly moving drag chain occasions, effectively prevent the cable winding, wear, pull off and scattered, mainly used in industrial electronic systems, automatic generation line, storage equipment, robots, fire fighting systems, cranes, CNC machine tools and metallurgical industry and so on.

Radiation-resistant drag chain cable, as the name implies, is based on the use requirements of the traditional automation field to increase the radiation resistance requirements, the cable not only has the characteristics of high-speed movement, but also meets the requirements of long-term stable and safe work in the radiation environment.

Manufacture of radiation resistant drag chain cable

1. Conductor structure

The cable should choose the most flexible conductor, such as bare copper or tinned copper. Generally speaking, the thinner the conductor, the better the flexibility of the cable; the appropriate conductor stranded structure and pitch are important factors to keep the conductor moving for a long time.

2. Core wire insulation

Cable insulation materials need to meet the requirements of radiation resistance while meeting the electrical performance. Our company uses highly flexible radiation-resistant insulation materials.

3. Cable

The cable structure must be wound around a stable tensile center with the best stranding pitch to achieve the requirement that the core wire does not shift when the cable is moving.

4. Shielding

The shielding layer is tightly braided in the inner layer of the sheath with optimized braiding angle and pitch. The loose braid will reduce the protection ability of EMC and the shielding layer will soon fail due to the fracture of the shielding. The tightly braided shielding layer has the effect of anti-torsion at the same time.

5. Sheath

The material with high flexibility, wear resistance, radiation resistance and high tensile strength is used as the sheath material to meet the requirements of drag chain and radiation resistance.

Radiation resistant drag chain cable assembly

With the rapid development of space technology and nuclear power technology in China, the types and specifications of connectors and cable assemblies required by various systems are becoming more and more diversified, and ordinary connectors and cable assemblies can no longer meet the model requirements. With its highly reliable aerospace-level interconnect product solutions, Yujie can provide high-frequency, high-reliability, small wire diameter, ultra-light weight, radiation-resistant aerospace-level cable assemblies. At the same time, Yujie also cooperates with international brand manufacturers at the technical level to jointly explore and develop products that adapt to market development.

Precautions

Radiation resistant tow chain cable in the actual work must pay attention to the minimum bending radius of the cable, at the same time, the two points of the cable must be fixed, or at least in the motion end of the chain must be fixed, the general cable moving point from the end of the chain should be 20-30 times the diameter of the cable.
