JIADING District plans to invest around 400 million yuan (US$63.3 million) in 2012 and 2013 in upgrading its power grid network, which will benefit 43,000 households and nearly 130,000 people upon completion.
This will be the first time for Jiading to upgrade its low voltage power distribution network on a large scale, according to the Jiading Power Supply Co.
Under the project, the power company will increase the insulation rate of its 10-kilovolt lines, change inefficient transformers and upgrade aging power equipment. It will also help change the old power meters in old residential quarters.
The project will be completed in two phases, with the first already starting in early February.
At Jiafu Community in Juyuan New Area, which was part of the first phase project, power transformers on three power poles have been replaced - half the size but twice the capacity compared with previous ones.
"We also introduced more wires of larger capacity and adjusted the location of power poles. By doing so, the power carrying capacity has been tripled, which will benefit the 264 households in the residential quarter," said Xu Dong, who is in charge of the Jiafu project.
"We are using more home appliances but bigger power consumption will often turn off the circuit breakers," a Jiafu resident surnamed Wang said. "That meant I couldn't turn on other high-power electrical appliances, while the air-conditioning was running. Now with the power network upgrades, we finally can use power without trouble. I'm really happy."
According to the local power supplier, the transformer capacity is around 100-200 KVA in Jiading's old community blocks - a low level easy to cause damage to high-power appliances. Upon upgrade, the average capacity will be increased to 315-400 KVA.
As a result, power failures caused by low voltage will decline sharply, even to zero during summer and winter, according to the power company.
