Busbar Insulation Heat Shrink Tubing

Yozonetech busbar heat shrink tubing provides insulation protection for busbars used in switchgear and substations. The product range includes WMPG voltage-class tubing and RSFRNH-BTM medium-voltage tubing, with different sizes and recovered wall thicknesses for application-specific selection.

✔ Multiple Voltage Classes: WMPG series options include 1 kV, 10 kV, 20 kV and 35 kV. RSFRNH-BTM is listed for applications from 1 kV to 24 kV.

✔ Electrical Insulation Protection: Helps protect busbars against accidental flashover, tracking and arcing, depending on the selected product.

✔ Material Options: WMPG uses cross-linked polyolefin, while RSFRNH-BTM uses radiation cross-linked, halogen-free compounds and is flame-retardant.

✔ Size and Color Selection: Choose according to busbar geometry, supplied and recovered diameters, recovered wall thickness, voltage class and installation requirements. WMPG is available in yellow, red, green, blue and black.

Product Selection

Keep WMPG 1 kV, 10 kV, 20 kV and 35 kV series separate. For RSFRNH-BTM, select by the minimum supplied ID and maximum recovered ID, then check the listed recovered wall. A voltage label does not establish clearance, creepage or qualification of the complete switchgear assembly.

How to Specify Your Requirement

Identify the model first, then compare the supplied dimensions, fully recovered dimensions and installation space. Specify operating conditions, required flame or halogen performance, color, length, quantity and packaging. Certification and test references apply to the stated model and must be matched to the supplied product.

Dimensions are in mm unless another unit is stated. Operating temperature, minimum shrink temperature, full-recovery temperature and aging-test conditions describe different requirements. Keep them separate when selecting and installing the product.

RSFRNH-BTM — Medium Voltage Cross-Linked Polyolefin Bus-Bar Tubing

Continuous operation is listed as -40°C to +110°C. The additional catalog statement about use at 175°C gives no duration or duty; obtain a confirmed specification before applying that temperature.

RSFRNH-BTM is made from specially formulated radiation cross-linked halogen-free compounds. The source states that it provides high resistance to tracking and arcing and improves busbar insulation in switchgear and substations. It is suitable for medium-voltage busbars, cable terminations and joints from 1 kV to 24 kV.

Applications and Installation

Use the selected voltage-class product as part of an engineered switchgear or busbar insulation system. Confirm busbar geometry, clearance, creepage and recovered-wall requirements; model voltage labels and laboratory values do not certify the finished assembly.

Preguntas frecuentes

Which model should I choose

Keep WMPG 1 kV, 10 kV, 20 kV and 35 kV series separate. For RSFRNH-BTM, select by the minimum supplied ID and maximum recovered ID, then check the listed recovered wall. A voltage label does not establish clearance, creepage or qualification of the complete switchgear assembly.

Are all models flame retardant

Use the flame-performance statement of the exact model. Halogen-free, low-smoke and flame-retardant are separate requirements. A category title does not establish a shared rating.

How do I choose the size

Select the model and compare its supplied size with the largest assembly dimension and its recovered size with the required final fit. Check wall, tolerances, length and packaging in the corresponding table.

Is shrink temperature the operating temperature

No. Shrink or recovery temperature is an installation condition. Continuous operating temperature and short-duration laboratory aging or heat-shock tests are separate values.

Are all performance values guaranteed limits

Keep the distinction between standard requirements and typical test results shown in the tables. Agree the exact specification, acceptance limits, test method and product documentation with the order.

Can I order custom colors lengths or packaging

Send the exact model, dimensions, color, length, quantity and packaging requirements. Availability and nonstandard options are confirmed with the quotation.

Request a Quote

Send the model, required size, application, operating conditions, quantity, color and packaging. For markers, include print format and printer; for busbars, include voltage class and geometry; for caps and connectors, include cable or wire dimensions.
