The Hubbell Style 600 amp Deadbreak Elbow can also be used to splice power cables by assembling multiple elbows using epoxy accessory products.

To order Modular Splicing Kits, simply build your catalog number using the table below.

To order Hubbell Modular Splicing kits you must first specify the splicing application by selecting the Splicing Code that represents your application.

Example: The application requires a separable connector with test point between two 25kV, 500kcmil power cables. Referring to the table below, the splicing code to be used is "2".

The basic Catalog Number will be 625L_. By inserting the splice code, "2" immediately following the "L" in the basic catalog number, the catalog number to order is a 625L2. All "non-size" sensitive components will be included in the kit when ordering. Therefore, you must order individually the "size sensitive" components. These are the Compression Connector (625L_ _) for aluminum and copper cable conductors and a Cable Adapter (625CA_).

The Compression Connector and Cable Adapter are selected by including the appropriate insulator code and/or connector size. The quantity of Compression Connectors and Cable Adapters should be the same as the number of elbows found in the splicing code table if you are making a kit. THESE COMPONENTS MUST BE ORDERED SEPARATELY FROM THE BASIC MODULAR SPLICE CATALOG NUMBER TO MAKE A KIT.

Reducing Tap Well (RTW)

The Reducing Tap Well provides a method to connect a 200 amp loadbreak or deadbreak molded rubber elbow to a 600 amp deadbreak elbow. This can be accomplished by replacing the Basic Insulating Plug with a Reducing Tap Well and an appropriate bushing well insert. Wrench holes are provided to tighten the Reducing Tap Well into a 600 amp deadbreak elbow by using a standard spanner wrench.

Connecting Plug (CP)

The Connecting Plug is required exclusively for applications involving the joining or connecting of two or more molded 600 amp elbows. The Connecting Plug incorporates a straight through aluminum bus for the transfer of current between the mating 600 amp elbows. Wrench holes are provided to tighten the Connecting Plug into a 600 amp Deadbreak Elbow by using a standard spanner wrench.

Basic Insulating Plug (BIP)

The Basic Insulating Plug is a key component of every Hubbell 600 amp Deadbreak Elbow Kit, whether for applications requiring cable connections to switchgear or transformers or splicing applications utilizing the Hubbell multipurpose junction offering up to six connecting positions. The Basic Insulating Plug is required to secure the molded rubber 600 amp elbow in place. The one-inch hex located on top of the Basic Insulating Plug doubles as a means of tightening the molded rubber elbow on to its mating part and also as a capacitive test point.

Insulating Cap (IC)

The 600 amp insulating cap isolates unused 600 amp interfaces. It is insulated and fully shielded to provide submersible protection for energized 15 and 25kV deadbreak interfaces. To avoid low-energy discharge from the outer conductive shield, the 36" long braided lead wire should be grounded. The insulating cap meets IEEE 386 and is rated for both 15 and 25kV.

Bushing Extender (BE)

The bushing extender is used to increase the distance between the 600 amp bushing interface and the 600 amp T-body elbow. The extender is insulated and shielded to protect deadfront integrity. The bushing extender is rated for both 15 and 25kV and fully complies with IEEE 386.

-top of page-

Bushing Adapter (BA)

The Bushing Adapter provides a means to reduce a 600 amp bushing to a 200 amp loadbreak interface. The BA is fault close rated for 10,000 amps and complies with IEEE Std. 386. The BA is available in both 15kV and 25kV ratings.

Insulated Parking Bushing (SOP)

The 25kV Insulated Parking Bushing meets the full requirements of the IEEE 386 specification. The bushing provides a single deadbreak interface used to isolate and sectionalize an energized cable.

The Insulated Parking Bushing is designed to be installed in the parking stand mounted on a transformer or other device. A grounding lug is provided on the bracket for attachment of a ground wire.
