Compliance overview
Scope and applicability
This standard applies to the electrical equipment and related workplaces in power generation enterprises with facilities of 66kV and above, transmission, substation, and distribution enterprises with facilities of 35kV and above, and power consumption units with facilities of 220kV and above. It is mandatory for all relevant personnel and facilities operating within these voltage levels. Other power enterprises and consumers may refer to it as a guideline.
Technical requirements
GB 26860-2011 establishes the fundamental electrical safety requirements for personnel and workplaces in the electric power industry. It comprehensively outlines safety organizational measures, including the application of various work tickets (such as the first and second category work tickets), work permission, supervision, and termination procedures. Strict adherence to these administrative protocols is essential for operational compliance. The standard details safety technical measures that must be implemented before and during electrical work. This includes specific protocols for power outages, voltage verification, installation of grounding wires, and the proper placement of warning signs and barriers. It also covers general operational requirements for electrical equipment, emphasizing safe distances and operational sequences to prevent accidents. Furthermore, the standard provides specialized safety requirements for various high-risk scenarios, including live working, maintenance of generators and high-voltage motors, operations on SF6 electrical equipment, and work on secondary systems. It also addresses safety protocols for electrical testing and power cable operations, ensuring comprehensive risk management across different electrical tasks.
Testing methods
The standard includes a normative appendix detailing the testing items, cycles, and requirements for insulation safety tools. Key testing methods involve power frequency withstand voltage tests and DC resistance tests for equipment such as capacitive voltage detectors, portable short-circuit grounding wires, insulating rods, insulating boots, and insulating gloves. Regular testing according to these specified cycles is mandatory to ensure the integrity of safety equipment.
