Standard formulation for rural electrical ready boards: ensuring safety and leading the industry

As the core node of rural power supply, the standardized construction of rural lighting electrical ready boards is a key lever to ensure the safety of rural electricity consumption and promote the standardized development of the industry. Currently, with the deepening of the rural revitalization strategy, the rural electricity load continues to grow, which puts higher demands on the safety, reliability, and intelligence of electrical ready boards. Based on national mandatory standards and industry practices, the development of standards for rural lighting electrical ready boards needs to be carried out from the following dimensions:

1、 Security Performance: Building a Strong Firewall for Rural Electricity Use

Material and structural standards

Box material: Cold rolled steel plates or flame-retardant plastics are preferred, with a steel plate thickness of ≥ 1.5mm (floor cabinets ≥ 2.0mm) to ensure impact resistance and corrosion resistance.

Protection level: The outdoor electrical ready board should reach IP54 or above to prevent rainwater and dust from entering; Internal components need to undergo salt spray testing to adapt to high humidity coastal environments.

Fireproof design: The interior of the box adopts fireproof partitions, and rubber sheaths are installed at the cable inlet and outlet to prevent electric arcs from igniting combustibles. The Jiangyan District Power Supply Company has reduced the rural electrical fire rate by 65% by standardizing the fire prevention structure of electrical ready boards.

Electrical Safety Standards

Grounding protection: The electrical ready board must be equipped with a dedicated grounding strip, with a grounding resistance of ≤ 4 Ω; The metal shell is reliably connected to the PE wire to prevent electric shock accidents.

Overload protection: Install circuit breakers with rated current matching the line load to prevent fires caused by overload. Using circuit breakers to automatically cut off power when overloaded, ensuring the safety of electricity for villagers.

Leakage protection: 30mA/0.1s leakage protectors should be installed in humid rural environments to ensure personal safety.

2、 Installation specifications: Standardized operations enhance reliability

Installation position and height

The bottom edge should be at least 1.8m above the ground to avoid being touched by children; The distance between the operating handle and the side wall is ≥ 200mm, which is convenient for operation and maintenance.

Wiring and Identification Standards

Wire specifications: The secondary side wire adopts ≥ 2.5mm ² copper core insulated wire, and is separated by yellow, green, red, and black soft plastic sleeves for easy identification.

Clear identification: The circuit number, voltage level, rated current and other information inside the box are complete, and the distance between switches and fuses is ≥ 30mm to avoid misoperation. The standardized labeling of lighting electrical ready boards has increased the accuracy of reporting electrical faults to villagers by 80%.

Separation of N line and PE line: Set up a dedicated busbar, prohibit mixing, and prevent neutral line disconnection from causing voltage rise.

Energy management optimization

The time of use electricity pricing function guides villagers to use electricity during off peak hours and reduces electricity costs. For example, through time of use electricity pricing management, electricity expenses can be reduced by 25%.

Data statistical analysis helps property management optimize power supply strategies and improve energy utilization efficiency.

4、 Industry Leadership: Collaborative Development of Standards and Industries

Promote the upgrading of industrial clusters

Develop unified standards, eliminate outdated production capacity, and improve the overall level of the industry. For example, through standard guidance, the qualification rate of lighting electrical ready board products has been increased from 70% to 95%.

Strengthen government enterprise cooperation

The government has introduced subsidy policies to encourage enterprises to develop intelligent electrical ready boards; Enterprises participate in standard setting and provide feedback on market demand.

Carry out the "Safe Electricity in Rural Areas" activity, popularize safety knowledge of electrical ready boards through animation, picture books and other forms, and enhance the safety awareness of villagers.

Green and sustainable development

Promote energy-saving electrical ready boards, adopt low-power components and carbon emission measurement functions, and help achieve the "dual carbon" goal in rural areas.

Using recyclable materials to reduce environmental pollution and promote the green transformation of the industry.
