Cable bepa kana kraft bepa rakagadzirwa neisina kubvongodzwa kraft softwood pulp seyakabikwa, mushure memahara-fomu pulping, isina glue uye filler, wozogadzira mapepa ekugadzira, uye pakupedzisira kupatsanurwa kuita tepi mapepa zvigadzirwa. Inokodzera kuvharwa kwemafuta-bepa insulating tambo dzemapepa, iyo insulation pakati pekutendeuka kwemotor uye transformers, uye kuvharirwa kwezvimwe midziyo yemagetsi.
Iyo tambo bepa kana kraft bepa ratakapa ine zvinotevera maitiro:
1) Iyo insulating bepa yakapfava, yakaoma uye kunyange.
2) Yakanaka michina zvivakwa, yakasimba tensile simba, kupeta simba uye kubvarura simba, nyore kuputira.
3) Yakanaka magetsi emagetsi, yakakwira dielectric simba uye yakaderera dielectric kurasikirwa.
4) Kudzivirira kwekushisa kwepamusoro, kupikisa kwepamusoro uye vulcanization kuramba.
5) Pasina simbi, jecha uye conductive asidhi zvinhu. Kugadzikana kwepepa kwakanaka mushure mekurapwa mumvura inodzivirira.
Inonyanya kushandiswa mu insulation layer yemafuta-bepa insulated simba tambo, insulation pakati pekuchinja kwemamotor uye transformer, uye insulation yezvimwe midziyo yemagetsi, nezvimwe.
