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。

With a high temperature, corrosion resistance, heat shock, low thermal conductivity, high electric insulating strength and high elastic modulus properties.

具有耐高温、耐腐蚀、耐热冲击、低导热系数、高电绝缘强度和高弹性模量等特性。

Due to the concentrated electric field distribution at the gap, high local energy of porcelain insulators results in scorification and plastify, followed by the loss of insulating strength.

由于瓷绝缘子孔隙处电场分布集中。局部能量过高将导致瓷质逐渐烧熔塑化。

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.

本实用新 型不但耐热性能好，绝缘强度高、导热系数低，而且便于机械加工，可广泛 用于电热设备上。
