Why do angle towers make up only 10–15 % of a line yet drive so much of the steel budget? Because each one has to carry the transverse pull of every conductor where the route turns. That is the kind of question our team likes to work through on CR4. A typical example from our range is a 45 m double-circuit 220 kV angle tower for a 30° deviation: Q420/Q460 steel lattice, a minimum 85 µm hot-dip zinc coat for a 50-year design life, composite V-string insulators with more than 5,500 mm creepage, 2-bundle ACSR 400 per phase, and an OPGW earth wire with up to 96 fibres for SCADA links. Loads are checked to IEC 60826 and conductor ratings to IEEE 738. SOLARTODO LIMITED (Gaoyou, Jiangsu, China; Austin, Texas office; ISO 9001/14001/45001) also supplies smart poles and solar lighting.
