2. In pouring, pouring material is the key. It has a great influence on the reliability and stability of cemented pole. For example, Xiamen Huazhong Electric Switching Co., Ltd. uses the resin materials of Vantico, Switzerland, and adopts different formulas according to different current, etc. to meet different working conditions .
3. The APG process includes three processes: pre-mixing, automatic pressure gel, and solidification after molding.
4. Applicable system: 35 KV or below voltage level of the ground, small resistance grounding, arc coil grounding, direct grounding system;
Protection range: not only can be used for line protection, such as line protection, but also can be used for, PT, main change reserve protection, motor, capacitor, reactor protection .
