26/35kV AL/XLPE/CWS/SWA/PVC Three Core Power Cable (300-630 mm²)
Zhongdong Cable's 26/35kV large-section three-core power cable is engineered for high-capacity medium-voltage transmission, manufactured in accordance with IEC 60502-2 and IEC 60228. The large aluminium conductor cross sections from 300 to 630 mm² deliver lower electrical resistance and higher current-carrying capacity for demanding distribution routes.
The combination of XLPE insulation, copper wire screen (CWS) and galvanized steel wire armour (SWA) ensures stable dielectric performance, effective fault current return and outstanding mechanical protection for direct burial.

FAQ
Q1: What is the main installation consideration?
A: Due to higher voltage and larger size, proper cable handling and controlled pulling force are critical during laying.
Q2: Can this cable be used for long-distance underground routes?
A: Yes, but route design should minimize sharp bends and reduce installation stress to maintain insulation integrity.
