Distributor and consumer terminals are connected by the service mains. A distributor is an intermediary entity between the product producer and another entity in the supply chain or distribution channels, like a retailer, a system integrator (SI) or a value-added reseller (VAR). The distributor performs some of the same functions that a wholesaler does but generally takes a more active role.
Consumer terminal means personal computers, mobile devices or other access devices (including without limitation mobile phone, tablet and television) through which you access the Electronic Trading Service
Applications
(a). Extension of service line capacity is simple – Yes, if you wish to go from a single-phase to a three-phase supply for your home, it is simple to perform in an overhead SM and quite challenging in an underground SM.
(b) Defect location and correction are simple – If a fault develops in an overhead SM system, it is simple to locate the issue and fix it, while fault location in an underground SM system is much more challenging.
(c). Easy to Erection – Erection of overhead SM is simpler than that of underground SM. For example, excavating for pipes and purchasing materials are both quite expensive in underground SM.
(d). It Is Cheap – Compared to underground service mains, materials needed for overhead SM are less expensive.
