Construction and Installation

The high reliability of power equipment stems not only from manufacturing precision but also from every step of the installation and construction process. Huihai Electric Machinery Co., Ltd. holds a Class III General Contracting Qualification for Power Engineering Construction and a Class IV License for Installation (Repair, Testing) of Power Facilities. It boasts a project team with an average of 12 years of experience. The company can undertake the construction of power generation projects with a single unit capacity of 100,000 kW and below, transmission lines of 110 kV and below, and substations of the same voltage level. It can also undertake the installation, maintenance, and testing of power transmission, supply, and receiving facilities of 35 kV and below. The company possesses over 40 sets of major inspection and testing equipment and construction machinery, as well as an independent professional testing hall.

Huihai Electric Machinery has completed the erection of over 100 kilometers of 35kV double-circuit double-split tower lines, the laying of 140 km of 35kV and below cable lines, 5 substations, and over 10 10kV substations, achieving a 100% excellent project rate. From initial inspection to grid connection, we adhere to the principles of "standardized operations, full-process traceability, and zero-defect handover" for every project we undertake, ensuring that every terminal and every withstand voltage test withstands the test of time.

In power construction, there is no "good enough," only "acceptable or unacceptable." From the tightening torque of the first bolt to the final verification of protection settings, Huihai consistently upholds the bottom line standard of "doing it right the first time, successful power transmission the first time." Every test report and every supervisory acceptance record Huihai's reverence for safety and dedication to craftsmanship.
