24kV Ring Main Unit for Distribution Projects
24kV RMU project review with a 630 A main-busbar reference. Confirm function units, transformer protection, insulation, cable accessories and DTU scope with JCON ELEC.
Scope of supply
24kV RMU proposals are built from the required ring-network ways, transformer feeders, protection and automation interfaces. Main-busbar current, individual feeder ratings, insulation technology and expansion provisions must be checked separately.
Price and lead time follow the confirmed drawings, component brands and supply scope. The quotation must state packing, freight, destination, Incoterms and any site-service exclusions.
24kV RMU: reference ratings and configuration scope
Reference voltage: 24 kV; current: 630 A; short-time withstand: 20 kA (3 s).
Source: JCON product information. Confirm the applicable standard editions, authorization scope and test evidence for the offered assembly. A standards reference is not a certificate or test report.
Configuration routes
These are RFQ routes, not pre-engineered packages. Confirm the actual ratings, brands and verification basis before ordering.
| Application | Configuration to review | Buyer inputs |
|---|---|---|
| Ring incoming and outgoing waysRequest this configuration | Review ring-network switching ways and the required isolation/earthing arrangement against the SLD. | Number of ways, current for each way, fault duty, cable entry and fixed/extendable requirement. |
| Transformer feeder protectionRequest this configuration | Review fuse-switch or circuit-breaker protection as a project-specific choice, not a price-only substitution. | Transformer data, protection philosophy, relay and CT/PT needs, control power and cable terminations. |
| Automation and insulation optionsRequest this configuration | DTU/remote interfaces and SF6 or alternative-gas insulation are separately reviewed options, not default inclusions. | Required signals/controls, protocol, auxiliary supply, insulation restrictions and configuration-specific verification evidence. |
Documents and acceptance scope
Agree document deliverables and checks against the offered assembly. A company certificate or standards reference does not verify every configuration.
