European XLPE-Insulated Medium Voltage Power Cables VDE 0295 and HD 383
Medium Voltage Power Cables up to 30 kV with XLPE-insulation The XLPE-insulation possesses very good electrical, mechanical and thermal characteristics in medium voltage networks. This type of insulation is excellent chemical resistant and also resistant to cold. Due to various advantages, the XLPE-insulated type has vastly displaced the traditional classical paper insulated types in many sectors. The XLPE-insulated medium voltage cables are designed with longitudinally water-proof. In comparison to PVC and paper-insulated cables, the advantages of XLPE-insulated medium voltage power cables are possessing a low dielectric factor. The good properties of XLPE-insulated cables remain constant at a long temperature range. These cables can be laid in earth, in air or in tubes.
Cable Installation
In order to avoid any damage, the XLPE insulated medium voltage power cables should be carefully laid and installed. It must be ensured that the cables should not be pulled over hard or sharp edges. The cable ends must be sealed water-tight. After cutting the length both ends must be sealed immediately.
An installation depth of 60 to 80 cm is recommended. Single conductor cables are normally arranged in a trefoil touching or triangular shape.
For installation in conduits, especially the influence of thermal insulation of air space between the cable and the inner wall of the conduit should be considered. The inner diameter of the conduit should be at least 1.5 times that of the diameter of the cable.
Main Technical Quota
1.DC resistance: conductor resistance of finished cable at 20'C per kilometer is not more than the following values.
| Nominal Section Area(mm 2 ) |
1.5 2.5 4 6 10 16 25 35 50 70 95 120 150 185 240 300 400 500 630 800 |

Packing and shipping: We are capable of meeting the strictest delivery schedules according to per purchase order. Meeting the deadline is always the top priority as any delay in the delivery of cable can contribute to overall project delay and cost overrun.
Cable is supplied in wooden reels, corrugated boxes and coils. Cable ends are sealed with BOPP self-adhesive tape and non-hygroscopic sealing caps to protect the cable ends from moisture. The required marking shall be printed with a weather-proof material on the outsides of drum according to customer's requirement.
