About This Item
C57.12.23-2002 is a technical standard for voltage connectors used in power and energy applications, covering high voltage up to 25,000 V, low voltage up to 600 V, and equipment rated 167 kVA and smaller. It helps define connector expectations for compact power apparatus where electrical performance, fit, and reliability matter. For engineers and buyers working with transformer-related hardware or similar installations, C57.12.23-2002 provides a clearer basis for selecting compatible components and evaluating compliance.
Overview of C57.12.23-2002
This standard addresses voltage connectors in an electrical power context, with scope limits that point to medium- and low-voltage equipment rather than large utility hardware. C57.12.23-2002 is relevant where connector design must support defined voltage levels and smaller kVA ratings, helping align product construction with expected service conditions. In practical terms, it serves as a technical reference for connector requirements, dimensional compatibility, and performance expectations within power equipment assemblies.
Typical use cases
C57.12.23-2002 is commonly applied to connectors used on transformers and related power apparatus operating within the stated voltage and capacity ranges. It may support selection and verification of components for distribution equipment, shop assembly, field replacement parts, and procurement specifications. The standard is especially useful when teams need to match connectors to a defined voltage class and ensure that the selected hardware fits the electrical and mechanical needs of the installation.
Why it matters
Using C57.12.23-2002 can improve consistency in design and purchasing decisions for voltage connectors used in power systems. It helps reduce the risk of mismatched parts, unclear requirements, and avoidable installation issues. For organizations responsible for engineering review, testing, or equipment sourcing, the standard offers a common technical basis for comparing products and checking whether connectors meet the expected service profile. That support is important in applications where reliability and safe operation are essential.
