The status quo of China’s gold fittings industry

Gold fittings play an important role in power transmission and transformation engineering.Product quality is not only related to the safe operation of power grid, but also related to the safety of personal property.As early as 1986, the relevant departments of the State Council brought electric power fittings into the production license administration.

Since the implementation of the production license management of electric power fittings, there are more than 200 forensic enterprises, including 3 foreign-funded enterprises, a total of more than 400 product units.Manufacturers are distributed all over the country, Jiangsu, Zhejiang, the two provinces the most, accounting for more than 1/3 of the total, Hebei, Sichuan province and the second.Different product units, different varieties, the production scale is very different, the annual output value from several million yuan to several hundred million yuan.At present, there are about 30 enterprises with the production qualification of 500KV power transmission and transformation fittings, 15 enterprises producing 750V power transmission and transformation fittings, and 11 enterprises producing 1000KV ULTRA-high voltage power transmission and transformation fittings.These enterprises have strong production capacity and high management level, and are in the leading position in the current electric power fittings industry.

The number of product units obtained by forensic enterprises is different. There are more than 50 enterprises obtaining 4 product units. Enterprises with the production qualification of 500V or above wiring fittings basically have 4 product unit certificates.Most enterprises with 3 or 2 product units do not produce malleable iron products for environmental reasons.Most of the enterprises with one product unit are malleable cast iron products or pretwisted gold fittings.Malleable cast iron and gold manufacturers in Shanxi, Sichuan and Hebei provinces more.Pretwisted metal fittings are mainly matched with OPGW and ADSS fiber optic cables, and more than 10 manufacturers such as Beijing PLP and Shijiazhuang Huaneng have been established.Enterprises with 1 product unit also only produce anti-vibration hammer or insulated wire supporting fittings, which are generally not large in scale.
