PowerGuard AL 35kV 100% TR-XLPE CN XLPE UL Type MV-105 Electrical Properties (TREFOIL TOUCHING)
PowerGuard® AL 35kV 100% TR-XLPE CN XLPE UL Type MV-105 Electrical Properties (TREFOIL TOUCHING)
NOTESConductor ampacities are based on the following:
• Load factor of 100% or 75%• Earth thermal resistivity of 0.900ºC-m/W• Ambient earth temperature of 20ºC• Maximum conductor operating temperature of 105ºC• Concentric neutral wires grounded at both ends (shield circulating currents flowing)• Minimum separation of 3 m or 9.8 ft from any other underground electrical system or heat source• Maximum load variation between phases of 10%• Maximum 910 mm or 36 in depth of burial• Cable arrangements:○ Trefoil and touching○ Flat and touching○ Flat and spaced 190 mm or 7.5 in, center-to-center• The ampacity values calculated may be limited by the maximum earth interface temperature due to soil moisture migration or dry out, and has not been considered here.
