Introduction
Product Description
Used for primary and secondary overhead distribution where limited space is available or desirable for rights of way. Installed as an uninsulated conductor; however, covering is effective in preventing direct shorts and instantaneous flashovers should tree limbs or other objects contact conductors in such close proximity. The resulting close-proximity configuration minimizes the amount of space and hardware required for line installation; particularly useful in congested areas such as alleyways or tight corridors.
1. Rated voltage U is 11kV. The cable can be used for the single-phase grounding failure time is generally not more than 1 minute each time, can also be used for the longest time not more than 8h, the annual accumulation not more than 125h system.
2. The cable laying temperature should not be lower than -20℃
3. The maximum temperature of the cable during short circuit (the longest duration is not more than 5s) : XLPE insulation -- 250℃; High density PVC insulation -- 150℃
4. Minimum allowable bending radius of cable: Single-core cable -- 20 (D+d) mm; Multi-core cable - 15 (D+d) mm. D, d are the outer diameter of the cable and the nominal diameter of the conductor respectively
