The mining sensor optical cable (SCTXG3H-4.0-BL) is a specialized sensing cable designed for monitoring environmental safety in flammable and explosive environments such as coal mines and metal mines. The cable is composed of a stainless steel seamless tube, reinforced with stranded stainless steel wires, and a high-flame-retardant sheath. Due to the use of stranded steel wires with strong tensile strength for reinforcement, it exhibits excellent tensile, compressive, and explosion-resistant properties, enabling it to adapt to the complex environment underground and resist damage caused by severe accidents such as rockfall and landslides, ensuring the normal operation of sensors.
