Nezve zvigadzirwa zvekuumba isu tine marudzi maviri ezvigadzirwa, ari kupisa shrink cable end caps uye heat shrink cable breakout. Heat shrink cable end cap ijekiseni-yakaumbwa ne polyolefin uye ine UV uye abrasion kuramba. Hot melt adhesive yakaputirwa mune inotenderera chimiro mukati mechubhu, ichipa yakavimbika mvura uye kudzivirira kwekudzivirira kune yakachekwa pamusoro petambo kana tambo dzakazadzwa nemhepo. Heat shrink breakout, yakagadzirwa nezvinhu zvinopisa zvinonyunguduka uye muchinjiko-yakabatana polyolefin layer, uye ine yakanakisa yekuisa chisimbiso kuita, dziviriro inonyanya kushandiswa mukuvhara uye kuvhara pazasi voltage magetsi tambo bazi.
