The role of the power cable insulation layer of mining cable

The Role and Function of the Insulation Layer in Mining Cables The insulation layer of a mining cable's power core plays a crucial role in ensuring safe and efficient power transmission. It determines the cable’s insulation level, which is a key factor in distinguishing high-voltage cables from low-voltage ones. This layer is essential for maintaining normal electrical operation. If the insulation deteriorates, it can lead to leakage currents. These currents, when significant enough, can be detected by protective devices, triggering a trip to prevent damage or hazards. In addition to the insulation layer, mining cables also feature a semiconductor shielding layer on the power core. This layer serves two main purposes: first, it conducts electricity, allowing leakage currents to flow through specific paths (such as codes 3, 5, and 4) when the insulation fails; second, it prevents interference between the power core and other signals, ensuring signal integrity. Another important component is the grounding core, typically labeled as "4," often referred to as internal grounding. All mining equipment must have an internal grounding point connected to this core. Its function is to safely direct any leakage current into the earth, preventing electric shocks and reducing the risk of electrical faults. It’s also important to note that when connecting cables or linking them to devices, the power cable should never be directly connected to another cable. Doing so may cause false leakage fault alarms, leading to unnecessary shutdowns and potential safety issues. Our factory solemnly guarantees: 1. Every product comes with a quality assurance certificate, ensuring that no substandard products leave our facility. 2. We provide product quality tracking services for two years and maintain customer service records for up to 20 years. 3. In case of quality issues, we guarantee returns, replacements, and full satisfaction of customer needs. Product Specifications: We customize the number of cables based on customer requirements. For example, orders of 100 meters are priced at 100-200 meters, depending on the quantity. The pricing is subject to change based on copper price fluctuations, and detailed quotes can be obtained through direct consultation.
