Nitrile cold-resistant flat cables feature cold resistance, softness, wear resistance, and oil resistance, suitable for power transmission lines and control, lighting, and communication lines for mobile electrical equipment such as trolleys and conveyors with special requirements for cold resistance and oil resistance at AC rated voltages of 0.6/1KV and below. This product is widely used in industries such as metallurgy, power, shipping, and ports. The conducting cores are designed with a soft structure to ensure excellent flexibility of the cable.
Detailed Information on Nitrile Flat Cables
I. Overview:
Nitrile flat cables feature cold resistance, flexibility, wear resistance, and oil resistance, suitable for power transmission lines and control, lighting, and communication lines for mobile electrical equipment such as trolleys, conveyors, and transmission machinery with special requirements for cold resistance and oil resistance at alternating rated voltages of 0.6/1KV and below. This product has been widely used in industries such as metallurgy, power, shipping, and ports. The conducting cores are made with a soft structure to ensure good flexibility of the cable.
Insulation and protective layer materials use polyethylene, enhancing the cable's softness and its resistance to corrosion and cold.
Color-coded insulated wire cores for easy laying and installation.
Available for customer requirements, additional wire ropes or other load-bearing elements can be added to both sides of the cable core (YVFB-G model).
II. Features:
Especially soft, highly resistant to bending, smooth in movement, without twists.
Indoor and outdoor, adaptable to temperature, resistant to acids, alkalis, oils, and salts.
Material selection is stringent, craftsmanship exquisite, performance reliable, and lifespan long-lasting.
