【摘要】 用于减少复合绝缘子发生脆断的耐酸芯棒的性能稳定性取决于芯棒中起粘合纤维作用的树脂的防护性能。通过分析论证 ,认为采用无捻直接粗纱纤维拉制芯棒和提高芯棒纤维间树脂固化度 ,可以避免酸介质进入内部腐蚀纤维 ,保证耐酸芯棒性能的稳定性。同时也得出芯棒长期承担较大载荷对其树脂防护性能影响不大的结论。更多还原

【Abstract】 The acid resistant stability of the core bar for reducing the break of the compound insulator is dependent upon the prevention performance of the adhesive colophony. It is considered that the core bar made of coarse gauze fiber combined with improving the colophony solidity in the core bar can prevent acid content from penetrating the core bar inside, eroding the fiber. This core bar is durable even in the condition of big loading.更多还原
