Busbar Insulation Heat Shrink Tubing
Product Overview
Cross linked insulation sleeves for switchgear and substation busbars
Yozonetech busbar heat shrink tubing covers WMPG voltage-class series and RSFRNH-BTM medium-voltage tubing. Selection depends on busbar shape and dimensions, voltage class, recovered wall and the complete insulation-system design.

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.
Product Range
WMPG — Heat Shrink Busbar Tube
RSFRNH-BTM — Medium Voltage Cross-Linked Polyolefin Bus-Bar Tubing
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.
WMPG — Heat Shrink Busbar Tube
WMPG is a cross-linked polyolefin heat-shrinkable busbar tube designed to provide insulation protection for busbars in switchgear and substations. The source describes protection against accidental flashover and leakage caused by small animals, reduction of busbar clearance requirements, and available yellow, red, green, blue and black colors.

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.
Frequently Asked Questions
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.
