35kV Three-Core Outdoor Heat Shrink Termination Kit

An RFQ reading “35kV outdoor termination, three cores, 500 mm², 20 sets” may appear complete. It identifies a product family and a nominal conductor size, but it leaves several purchasing decisions unresolved: the exact cable voltage designation, the number of cable ends, and the documentation required for project acceptance.

RIKI’s 35kV three-core outdoor heat shrink range is listed for 21/35kV and 26/35kV XLPE-insulated power cables. Its ordering table has three conductor-size groups: 50–120, 150–240 and 300–500 mm². The upper group includes 500 mm²; a 630 mm² option is not listed for this product family.

Check the Full Cable Voltage Marking

The manufacturer’s catalog lists two cable voltage designations under its 35kV heat shrink accessory range. That is useful for identifying the product family, but it does not mean that every cable construction with either designation automatically matches the same physical kit.

The project cable specification should identify the actual voltage marking, insulation outside diameter, conductor material and metallic-screen construction. These values must be checked against the selected termination and its applicable technical documentation.

Count Cable Ends, Not Just Three-Phase Circuits

A three-core termination serves a different purchasing unit from a single-core termination. The selected three-core arrangement is intended for one three-core cable end, where the three conductors are prepared as separate terminations above a common cable breakout.

For example, a cable run requiring termination at both ends involves two cable-end termination locations. The purchase order should state the number of complete three-core termination kits required at those locations, rather than treating three phase conductors as three independent kit orders.

Confirm how the supplier defines and packs each kit before finalizing the quantity. The product photo is not sufficient evidence of the commercial packing unit or the complete accessory list.

A Similar-Looking Kit Is Not Proof of Interchangeability

Outdoor heat shrink termination photographs from different voltage classes may show similar red insulation tubes, rain sheds and black breakout components. Their visual similarity does not establish equivalent voltage ratings, recovery dimensions, stress-control arrangements or environmental performance.

The illustrated RIKI kit includes multiple black sleeves, three long red tubes, red rain sheds and other jointing accessories. These visible components help identify the product type, but the exact material specification, installation sequence and supplied quantities should be checked against the bill of materials for the selected size.

Document Review Before Project Acceptance

For a project requiring technical approval, the catalog’s general test figures should be distinguished from a test report identifying a particular termination configuration. RIKI publishes 35kV-series electrical test references, including a wet power-frequency withstand figure of 104kV for one minute. This catalog entry does not independently prove that every ordering code has an individual third-party certificate.

Before submitting the product for approval, buyers should establish which technical drawings, test reports, installation instructions and applicable standards are required by the project. Any supplied document should be checked for product scope and relevance rather than accepted solely because it displays the correct voltage class.

For an exposed outdoor installation, the project must also establish the required surface insulation, pollution performance, cable-screen treatment and terminal clearance conditions. The number of rain sheds visible in the photograph does not prove a particular creepage distance or pollution classification.

Purchasing decision: select the conductor-size group, then verify the full cable specification, package contents, quantity per cable end and project acceptance requirements. These checks are necessary before approving the final supply configuration.
