YHD low temperature resistant rubber sheathed cable is a type of rubber sheathed cable specifically designed for extreme low temperature environments. It has good cold resistance, flexibility, and resistance to mechanical damage, and is widely used in polar scientific research, frozen storage, cold region engineering machinery, refrigerated truck power supply, and other scenarios.
Key selection points
(1) Temperature level
Specify the minimum ambient temperature (such as -40 ℃ or -60 ℃) and select the corresponding cold resistance level.
(2) Conductor and sheath
Conductor cross-sectional area: selected according to the current load (e.g. 10A load requires ≥ 1.5mm ²).
Sheath material:
Chloroprene rubber (CR): comprehensive cold resistance and wear resistance.
Silicone rubber (SIR): superior ultra-low temperature performance (-60 ℃), but high cost.
(3) Certification standards
National standard: GB/T 5013.8 (General standard for rubber sheathed cables).
International certifications: UL (United States), CE (European Union), GOST (for use in cold regions of Russia).
Precautions for use
Installation and maintenance
Bending radius: ≥ 6 times the outer diameter of the cable (to prevent sheath cracking).
Avoid sharp angle friction: Use protective sleeves when dragging on icy or snowy ground.
Regular inspection: Low temperature may cause the sheath to harden, and it is necessary to check for cracks.
Electrical safety
The conductor resistance increases at low temperatures, and voltage drop needs to be calculated (especially for long-distance transmission).
Cold resistant sealant (such as silicone) is used at the joint to prevent water and moisture.
