Explanation of Quality Feedback on Zhejiang SanGao Electric’s Products in Shenzhou-5 Manned Spacecraft Project

Zhejiang SanGao Electric Co., Ltd.:

The 10KV power distribution room of the Shenzhou-5 Manned Spacecraft Project at China Jiuquan Satellite Launch Center has adopted products such as ZW32-12 load switches, FN5-12R load switches, and HY5WS-12.7/50W arresters produced by Shanghai SanGao Electric Co., Ltd. During the usage, the products manufactured by your company have demonstrated leading technology, reliable quality, excellent performance, and timely after-sales service. Particularly during the launch of the Shenzhou-5 Manned Spacecraft, they played an important role in the successful completion of the power security task. It is hoped that your company will continue to uphold the principles of abiding by contracts, keeping promises, emphasizing quality, and providing timely services, and make greater contributions to the national defense cause.

What Products Did Zhejiang SanGao Supply for Shenzhou-5?

The Shenzhou-5 Manned Spacecraft Project at China’s Jiuquan Satellite Launch Center relies on a 10KV 配电室 (power distribution room) to keep operations running. For this, Zhejiang SanGao Electric provided three key products:

●  ZW32-12 type load switches

●  FN5-12R type load switches

●  HY5WS-12.7/50W type  (surge arresters)

(October 15, 2003 is the key date for China's first manned space flight. At 9 o'clock on the same day, the Shenzhou-5 manned spacecraft lifted off from the Jiuquan Satellite Launch Center.)

These products were installed in the project’s 10KV power distribution room, a critical hub for keeping the launch center’s electrical systems stable.

How Did These Products Perform?

When it comes to high-stakes missions like launching a manned spacecraft, reliability isn’t optional. Here’s how Zhejiang SanGao’s products measured up:

●  Leading technology: The designs met the strict technical standards required for space mission infrastructure.

●  Reliable quality: They worked without fail, even under the pressure of continuous operation.

●  Strong performance: They maintained stable output, no glitches or breakdowns.

●  Quick after-sales support: Whenever there was a need, the team at Zhejiang SanGao responded fast.
