1.Electrical insulation - The epoxy coating provides electrical insulation between individual bus bars and prevents short circuits.
2.Corrosion protection - Epoxy coatings protect the copper bars from oxidation and corrosion.
3.Mechanical protection - The coating protects the bars from physical damage during handling and installation.
4.Dielectric withstand - Epoxy has good dielectric properties and can withstand high voltages without breakdown.
5.Noise damping
