CHINA-GRID POWER TECHNOLOGY CO.,LTD. has a long experience in production and research of holding pole clamps. In 1995, it launched the third generation of holding pole clamps.

In 2009, the product design and forging process were further improved, the cross section of the neck of the clamp was increased, and the high current withstand capability of the clamp was improved, which was called improved clamp clamp.

Because its performance is obviously superior to the second generation and the third generation products, it is recommended to the majority of users.
