Automatic Wiring System for Medium Voltage Switchgear

Product Specifications

Technical details and manufacturing context for Automatic Wiring System

Definition

The Automatic Wiring System is a specialized subsystem designed for use within Medium Voltage Switchgear Assembly Systems. Its primary function is to automate the routing, positioning, and termination of electrical wiring between key components such as circuit breakers, busbars, protection relays, and control panels. By automating these processes, the system ensures precise, consistent, and efficient electrical connections while adhering to safety standards and reducing manual labor. The system operates using programmable robotic arms guided by CAD/CAM data. It selects appropriate wire types, measures required lengths, strips insulation, and terminates conductors at designated connection points. Integrated sensors provide quality control and alignment verification throughout the process. The system is designed to handle a range of parameters typical for medium voltage switchgear, including rated voltages from 12 to 40.5 kV and rated currents from 630 to 3150 A, as referenced in IEC 62271-200. It accommodates wire cross-sections from 1.5 to 240 mm² per IEC 60228, with wire processing speeds of 0.5 to 2.0 m/s and strip length accuracy of ±0.5 mm. Crimping forces range from 10 to 50 kN, referencing IEC 60352-2. The system operates within an ambient temperature range of -5 to 55 °C and relative humidity of 5 to 95% (non-condensing), per IEC 60068-2 and IEC 60068-2-78. It offers ingress protection ratings from IP20 to IP54 (IEC 60529). Power supply is single-phase AC 220–240 V (IEC 60204-1), with total power consumption between 2 and 5 kW. Pneumatic actuators require compressed air at 0.6–0.8 MPa (ISO 8573-1). The system weighs approximately 800–1500 kg and requires a floor space of 2.5–4.0 m². All listed values are reference ranges; actual model-specific values and compliance must be verified with the legal manufacturer or supplier.

Working Principle

The system uses programmable robotic arms guided by CAD/CAM data to automate wiring tasks. It selects the appropriate wire type, measures the required length, strips insulation, and terminates conductors at designated connection points. Sensors integrated into the system perform quality control and alignment verification, ensuring accurate and consistent connections. The process is designed to handle various wire cross-sections and crimping forces, adapting to the specific requirements of medium voltage switchgear assemblies.
