The results show that the long rod insulator features light weight, better anti-ageing performance, better anti-pollution behaviour, high tensile strength, puncture-proof and easy maintenance.
结果表明，棒形悬式瓷绝缘子重量轻，抗老化性能好，耐污性能较好，拉伸强度高，不可击穿，使用维护简便。

Therefore, the insulator should have both good electrical properties and sufficient mechanical strength.
因此，绝缘子既要有良好的电气性能，又要有足够的机械强度。
3
Ceramic insulator provides stronger resistance against thermal shock, greater mechanic and electric strength and reliable insulation.
