Under what circumstances is it necessary to use high flexibility cables that are cold resistant and low temperature resistant?

Many customers choose high flexibility cable without considering the temperature of the usage environment. Ordinary high flexibility cables will become stiff in low temperature environments, such as below -20 ℃, and the outer sheath will crack when moving back and forth.

So when using high flex cable in extremely cold places, it is necessary to choose cold resistant drag chain cables.

Low temperature resistant and highly cabo flexível is a special cable designed for extreme cold and frequent bending/dragging scenarios. Its core is to maintain softness, non brittleness, and electrical stability even at temperatures ranging from -40 ℃ to -60 ℃.

Core characteristics and design considerations of cold resistant cable

The design of low temperature resistant drag chain cable aims to solve the problems of conventional cables becoming hard, brittle, and cracking at low temperatures, ensuring reliable operation even in cold chain logistics, outdoor cold environments, or cold storage scenarios, following the drag chain system for frequent reciprocating movements. Its key features include:

1.Excellent low temperature resistance: By using special low temperature resistant materials such as polyurethane PUR, thermoplastic elastomer TPE/TPU, PVC cannot be selected, and the cable can remain soft at extreme low temperatures of -20 ℃, -40 ℃, or even -60 ℃ without brittleness or breakage. ‌‌

2.Comprehensive environmental tolerance: In addition to low temperature resistance, this type of cold resistant cable usually also has oil resistance, wear resistance, UV resistance, hydrolysis resistance, and good shielding performance (anti electromagnetic interference) to adapt to complex industrial environments. ‌‌

Key technical parameters and material selection for cold resistant flexible wire

When selecting or evaluating low-temperature drag chain cable, it is important to pay attention to the following technical parameters, which directly determine the applicability and reliability of the cable in specific environments. ‌‌

1.Temperature range: This is the most critical parameter. The temperature resistance performance of different sheath materials varies significantly:
● PVC sheath: The temperature range for mobile applications is usually -5 ℃ to+70 ℃, and for fixed installations it can reach -40 ℃ to+80 ℃. ‌‌

● PUR (polyurethane) cable sheath: superior performance, can reach -25 ℃ to+80 ℃ for mobile applications, and can reach -40 ℃ to+90 ℃ for fixed installation; Customized models can meet extreme demands of -60 ℃ or even lower. ‌‌

● TPE/TPU and other elastic materials are also commonly used in low temperature resistant designs, providing wide temperature range performance. ‌‌

Typical application scenarios of cold resistant, low-temperature resistant, and highly flexible cables

Low temperature resistant drag chain cables are widely used in automation systems that require dynamic operation under cold conditions.

1.Logistics and Warehouse Automation: Cold chain logistics sorting systems, shuttle cars, conveyor lines, AGV vehicles and other mobile equipment in low-temperature vertical warehouses (cold storage) are their main application scenarios. ‌‌

2.Industrial automation equipment: mobile component connections for CNC machine tools, industrial robots, robotic arms, automated production lines, etc. in cold workshops or outdoor environments. ‌‌

3.Large cranes and port equipment.

4.Special equipment and fields: medical devices (such as cryotherapy equipment), refrigeration equipment (cold storage, refrigerators), complete sets of petroleum equipment, power stations, and outdoor operation equipment in alpine regions.
