15kV 200A Bushing Extender Holder
The RIKI 15kV 200A bushing extender holder is a separable cable connector accessory for transformer and switchgear connection assemblies. Its ribbed insulating body incorporates a rain-shed profile, and the catalog identifies mating arrangements involving bushing joints, rotatable feedthru inserts and surge arresters. Buyers should verify the equipment interface, physical dimensions and required matching components before selecting it for a new installation or replacement.
An Extended Bushing Connection Has Two Interfaces to Get Right
An extended bushing holder may be selected because of the equipment’s connection arrangement, but the word “extended” does not tell a buyer which mating components will fit. Two connection points need attention: the apparatus-side mounting interface and the accessory fitted to the exposed end.
RIKI identifies this 15kV, 200A model as a bushing extender holder for transformers, outdoor cable distribution cabinets and switchgear. The catalog also describes connections involving bushing joints, rotatable feedthru inserts or surge arresters. Those are application possibilities, not confirmation that every accessory with a 200A marking can be fitted directly.
The Mating Interface Determines Compatibility
A 200A current rating identifies an electrical class. It does not fully describe the connector profile, mounting dimensions or attachment method.
When replacing an existing holder, record the original component model and examine the equipment connection drawing. The mating accessory also needs to be identified. A bushing insert, a bushing well and an extended holder are related components, but they perform different functions within a separable connector assembly.
For a new installation, the equipment supplier should confirm the required interface geometry and connection arrangement before the accessory order is approved. This is more useful than choosing a part solely because the voltage and current markings match.
Why the Insulating Body Has Ribs
The red product photograph shows a series of closely spaced external ribs below the main body. RIKI’s catalog describes a special rain-shed structure intended to increase the surface creepage path.
This geometry is relevant to equipment installations where the insulating surface may be exposed to moisture or contamination. Yet the visible ribs do not establish a numerical creepage distance, pollution class or specific outdoor qualification. These values should come from the applicable product drawing and test documentation.
The color of the insulating body is not an electrical specification. The supplied red product image and the black catalog illustration should be associated with the confirmed model, while any color-specific material or test requirements must be checked separately.
Do Not Confuse a 200A Holder with a 600A Conversion Accessory
RIKI’s accessory catalog contains another product described as a 600A bushing extender. That product has a separate model designation and a different stated purpose involving a 600A-to-200A connection arrangement.
The present 15kV 200A extender holder should not be described as a universal 600A-to-200A adapter. Its intended connection and electrical rating must be established from the actual holder model and the approved mating components.
This distinction matters when a buyer submits a photograph of an existing transformer bushing but does not identify the interface. A voltage rating and an external shape are not sufficient to decide whether a conversion component or an extended 200A holder is required.
What to Check on a Replacement Order
The existing connection location can impose dimensional restrictions. Available projection from the equipment wall, nearby accessories and access to the mating connection may affect whether the replacement will fit.
Ask for the apparatus drawing, original part identification and details of the intended mating component. If this is a replacement order, photographs of the existing installation can help identify the arrangement, but they do not replace a dimensional drawing.
Confirm the connection interfaces, mounting dimensions and any required accessories before ordering. The current catalog does not publish a verified extension length or a complete list of compatible mating models for this specific holder.

The 15kV and 200A ratings and application description follow the published RIKI catalog. Interface dimensions, mating-component compatibility, exact creepage distance, loadbreak switching capability and IEEE 386 conformity are not established by the catalog information provided here. These details require confirmation for the selected model and equipment assembly.
Frequently Asked Questions (FAQ)
Is a bushing well extender the same as a loadbreak bushing insert?
No. A bushing well extender holder and a loadbreak bushing insert have different functions in a separable connector assembly. A loadbreak bushing insert is designed to mate with a suitable bushing well and compatible elbow connector. The extender holder is a separate apparatus accessory, so its mounting arrangement and mating interfaces must be checked independently. Matching 15kV and 200A ratings do not establish direct interchangeability.
Can this holder be used with a rotatable feedthru insert or surge arrester?
The RIKI catalog mentions rotatable feedthru inserts and surge arresters among the associated connection arrangements. However, the exact mating interface, voltage rating and accessory configuration must be verified for the selected combination. The catalog description does not establish compatibility with every 200A feedthru insert or surge arrester available on the market.
Can this 200A holder convert a 600A bushing into a 200A connection?
Do not use this model as a 600A-to-200A conversion accessory without specific technical confirmation. RIKI lists a separate 600A bushing extender product for conversion applications. This model is identified as a 15kV 200A bushing extender holder. The equipment’s existing bushing class and required connection interface should determine which accessory is selected.
Does the rain-shed structure prove suitability for every outdoor installation?
No. The external ribs provide a longer surface insulation path, as described in the product catalog, but the photograph does not establish a specific creepage distance or pollution rating. Outdoor suitability depends on the complete insulating assembly, environmental conditions and applicable qualification requirements. The required technical evidence should be reviewed for the intended installation.
Where an Extended 200A Apparatus Connection May Be Required
Transformer 200A Connection Assemblies
Extended bushing arrangements for suitable transformer outgoing connections, with the apparatus mounting profile and mating accessory verified before installation.
Outdoor Cable Distribution Cabinets
Equipment connection layouts requiring an extended insulated holder, subject to the cabinet's available clearance, environmental conditions and approved interface geometry.
Switchgear Accessory Connections
200A-rated connection assemblies where the selected bushing holder must coordinate with compatible feedthru or other associated accessories.
Existing Bushing Holder Replacement
Replacement procurement where the original holder model, physical mounting dimensions and receiving accessory need to be matched rather than selected by appearance alone.
