the altitude revision factors influenced by pressure on pollution insulating strength of insulators were calculated under light pollution degree.
计算了绝缘子在轻污秽度下污秽绝缘强度受气压影响的海拔修正系数。
the utility model is not only heat-resistant, with high insulating strength and low heat conductivity coefficient, but also easy to machine, and can be widely used on electric heating apparatuses.
