For the installation of high-voltage distribution system in Southeast Asian countries, there are the following precautions:

environmental factor

-Climatic conditions: Most parts of Southeast Asia have a tropical climate, and high temperature, high humidity and rainy weather are common. Therefore, electrical equipment and materials suitable for this climate should be used, such as distribution boxes, switch cabinets and other equipment should have good heat dissipation and moisture-proof performance. When installing, try to install the equipment in a well-ventilated place where it is not easy to accumulate water. For outdoor equipment, facilities such as canopy should be set up.

-Geographical factors: There may be complicated geological conditions in some parts of Southeast Asia. For example, in areas prone to earthquakes and with strong soil corrosiveness (near the sea), seismic design should be considered for the installation foundation of electrical equipment, and anti-corrosion measures should be taken for buried cables, grounding devices, etc., such as wrapping the grounding electrode with anti-corrosion coating.

Electrical standard difference

-Different Southeast Asian countries may have different electrical standards. It is necessary to carefully study the local electrical specification requirements such as voltage level (220V in some countries and 230V-240V in others), frequency (50Hz or 60Hz) and grounding system type. In the installation process, the selected electrical equipment and materials, including transformers, cables, switches, etc., must meet local standards to ensure the safe and reliable operation of the whole distribution system.

Safety and protection

-Safety against electric shock: Due to the high voltage of the high-voltage system, the construction personnel must strictly abide by the safety operation regulations when operating. In humid environment, more attention should be paid to prevent electric shock accidents. The metal shell of all electrical equipment should be reliably grounded, and the tools used should have good insulation performance.

-Fire and explosion prevention: Some countries in Southeast Asia may have inflammable and explosive places, such as oil depots and chemical enterprises. When installing the distribution system near these places, explosion-proof electrical equipment should be used, and electric sparks that may cause fire or explosion should be avoided during wiring.

Power supply stability

-The power supply in some Southeast Asian countries may be unstable, and voltage fluctuations and power outages may occur. When designing and installing the power distribution system, we can consider providing voltage stabilizing equipment and UPS (Uninterruptible Power Supply) to protect sensitive electrical equipment, and at the same time, we should set up reasonable protection devices, such as fuses and circuit breakers, to deal with sudden power failures.
