PH Series-Medium Voltage Busway
MV Cast Resin Insulated Busway(Aluminum Busway)
TECOBAR Medium Voltage Cast-Resin Insulated Busway is developed for power systems between 1kV~24kV. The product has features of safety and compact. It is designed to using insulation material to perform cast resin sealing to the copper (aluminium) conductor. The insulation material is cast resin containing non-organic volcanic rock and has excellent insulation characteristics and mechanical strengh, humidity-proof, non-combustible, and self-extinguishing features.

2.Voltage drop calculation
- △U =√3 x Is x L x (R cosθ+X sinθ) x 10-6
- △U =Voltage drop (Volts)
- Is =Load current (Amps)
- L =Line length (m)
- R =Resistance (μ Ω/m)
- X =Reactance (μ Ω/m)
- cosθ =Power factor
- sinθ =√(1-cos 2θ)
