In January 2018, Zugo Electrical Testing Co., Ltd. completed the pre-qualification test project for 330 kV cable system successfully in 365 days (8760h), which proved that our company has the service ability to provide ultra-high voltage cable system test for domestic and foreign customers.
In September 2016, Zugo has signed the contract for
outdoor prequalification test for 330 kV cable system. This prequalification
test for the cable system is designed to replace the past net tests, which
overcomes lax examinations during the experimental operation periods and
operational threats brought by the steadiness of the power grid, and
effectively guarantees the reliability of long-term operation of the cable
system. According to the standards and requirements of IEC62067-2011 testing,
the laying features of testing cables and analog cable circuits include
tunnels, direct burials, poling, terminal areas, direct sunlight areas and etc.
The wholes testing requires sustained and stable 323kV withstand voltage for 365
days, during which time thermal cycling tests should be conducted for at least
180 days.
Zugo Electrical Testing Co., Ltd actively
responds to the national proposal to build the "Belt and Road",
persists in bringing in and going out, following
the Principle of discuss together, co-construction and sharing, and
strengthening the opening and cooperation of innovative capabilities. Zugo formed
an open pattern for the interaction between main land and oversea, East and West.
Zugo has become the pioneer in opening the international cable testing market.
