Answer: An electrical distribution system is a network of components that safely delivers power to end-users. The key components include substations, which step down voltage from transmission lines; distribution lines, which are the overhead or underground cables carrying power; transformers (typically on utility poles or ground-level pads), which further reduce voltage for consumer use; and protective devices like circuit breakers and fuses, which ensure system safety and prevent overloads. We supply the essential tools for constructing and maintaining all these components.
