Stranded Copper Core EPR Insulation High Tensile Strength Rubber
Sheathed Flexible Power Cable for Industry and Heavy Industry Use
Rubber-sheathed cable is a type of movable cable with rubber as the
insulating and sheathed material. It features flexibility and
durability, and is widely used in various electrical equipment.
This Cable can be classified into three types based on the
mechanical forces they are subjected to: light, medium, and heavy.
The long-term allowable operating temperature of cables is
generally not more than 65℃. Rubber-covered cables can withstand
mechanical pressure and deformation, have good tensile strength and
impact resistance, and perform more persistently and stably in
high-frequency bending and twisting, making them suitable for
equipment that needs to be frequently moved or replaced.

Applications
Rubber sheath cables can withstand mechanical pressure and
deformation, have good tensile strength and impact resistance, and
perform more persistently and stably in high-frequency bending and
twisting, making them suitable for equipment that needs to be
frequently moved or replaced.The specific usage scenarios are as
follows:
- Industrial sector: Power supply for mobile devices including construction machinery
(excavators, cranes, concrete pump trucks) and industrial
automation equipment (machine tools, conveyor belts, robot drag
chain systems)
- Agricultural sector: Power lines for agricultural machinery (harvesters, tractors) and
agricultural electrification scenarios
- Construction sector: Temporary power distribution for construction site equipment,
lighting, and vibration rods
- Special environments: Port/ship shore power connections, outdoor installations (street
lamps, billboards), high-temperature areas (metallurgical furnaces,
boiler rooms with silicone rubber sheath variants)
