APPLICATION:
Iwo akajairwa simba single-core cables ane voltage range kubva 3.8/6.6KV kusvika 19/33KV uye frequency ye50Hz.. iwo anonyanya kushandiswa munzvimbo dzakasiyana-siyana dzakadai semagetsi emagetsi, mukati nekunze kuisa, mumapaipi uye tunnels, mumigodhi nemumigodhi, mukuvigwa zvakananga muvhu uye pasi pemvura pasi pegungwa, etc. Ivo vanokwanisa kumirisana nezvinodzvinyirira zvakanyanya uye mechanical kunze masimba, uye axial tensile forces.
