クラフト絶縁紙添加剤としてのn-butyl Carbamateの特性

抄録

Kraft paper is used for insulation in oil immersed equipments such as condenser, transformer. The reason is that Kraft paper has given satisfactory performance on electrical and mechanical properties.
As for life, however, thermal degradation occurs due to temperature rise in operation. Example of these kinds of the Kraft paper are cyanoethylated Kraft paper and dicyandiamide modofied paper. Moreover Kraft paper containing morpholine, oxyalkylamine, aromatic-polyamine, para-toluene-sulfoneamide, etc are well known.
This paper describes a thermal aging characteristics of new n-butyl carbamate modified Kraft paper, compatibility between n-butyl carbamate and polyvinylformal wire, thermal dissociation products of n-butyl carbamate and thermal aging characteristics of insulating oil.
