Types of underground cables - electricaleasy

Types of underground cables - electricaleasy

Underground cables are usually employed to deliver 3 phase power. A 3 cored cable is preferred up to 66 kV. Beyond that, insulation required for the cable is too much. For higher voltages, 3 cored constructions become too bulky, and hence, even with some limitations we employ single cored cables. [Also read: Electric power transmission system]

Capacitance of underground cables - electricaleasy

As we saw earlier in the construction of Underground cables, a cable is basically a set of one (or three) conductors surrounded by a metallic sheath.This arrangement can be considered as a set of two long, coaxial, cylinders, separated by insulation. The current carrying conductor forms the inner cylinder while the metallic sheath acts as the outer cylinder.

Effects of MV and HV cable capacitance on operational limits

DC cable systems do not have problems with cable capacitance charging. Overhead MV and LV DC systems are in use in distribution networks and could be extended to underground cable networks in cases where AC cable systems are being considered. DC cable systems have been installed in a number of countries, and low capacity DC, such as DC light .

Con ?? The DC hi-pot test can be a destructive test when performed on service-aged, MV cable insulation (as per an EPRI study performed in the 1990s). This test methodology is also blind to certain types of insulation defects and induces space charges that can aggravate existing insulation defects in aged extruded cables.
