ELCB is an acronym for Earth leakage circuit breaker, which is a device placed inside a water heater, commonly referred to as ELCB electric leakage breaker. This circuit breaker has the function of disconnecting the device from the circuit whenever an electrical leak occurs through the human body when touching the electrical parts of the device.
ELCB is to limit the incident of electric shock inside the machine, disconnecting the power when there is a problem, ensuring safety for human life as well as fire and explosion prevention.
ELCB is often used in both civil and industrial applications.
For the domestic electricity system, the installation problem is not difficult, but in industry, the anti-shock for workers and the prevention of electrical leakage for electrical equipment with large capacity requires a bridge. Automatic anti-shock, high-power leakage protection, and often has a much higher price.

After the fabrication process as cutting plate, bending, forming, automatic welding, drilling holes, we get poles checked before galvanized, hot dip galvanized and powder coating and finally we get poles checked according to client's requirements.
Inspection
To ensure the quality, we have professional technicists to inspect the poles during the manufacturing and before delivery.
We have Lab Test, Workload Test, Steel thickness Test, Galvanization thickness Test, etc.
Delivery
We normally use 40HQ containers and our Port limit weight for a 40HQ is 26 tons.
