Insulators are divided into line insulators and pillar insulators. The insulators used in overhead lines are called line insulators, and pillar insulators are mainly used in power plants. According to different purposes, line insulators are divided into suspension insulators and tension insulators. Suspension insulators are used to suspend overhead conductors. Tension-resistant insulators need to withstand the tensionofconductors.www.diandongmenc.com.cnwww.chongyajiann.cnwww.yanglaoyuanc.com.cn

According to the classification of insulating materials, there are three types of insulators: electric porcelain, glass and composite insulators.
