Thumela i-imeyileIlungele uthungelwano lwamandla olufana nezikhululo zamandla.Ukufakwa kwimibhobho, phantsi komhlaba nangaphandle.Nceda uqaphele: I-sheath yangaphandle ebomvu inokufiphala xa ibekwe kwimitha ye-UV.
Imigangatho:
Ukusasazwa komlilo kwi-BS EN60332
BS6622
IEC 60502
Iimpawu :
I-Conductor: Iikhonduki zobhedu ezixineneyo ezityaliweyo okanyeumqhubi we-aluminium
I-Insulation: ikhonkco lomnqamlezo we-polyethylene (XLPE)
Isikrini se-Metallic: isikrini seteyiphu yomntu ngamnye okanye sisonke
Isahluli: iteyiphu yobhedu ene-10% yokudibana
