Heat Shrink Cable Accessories That Keep Power Networks Energised
Termination and joint kits stress control and insulation tubes molded parts busbar insulation and repair sleeves for cable from 0.6/1 kV to 26/35 kV. Compounded extruded irradiated and tested in our own plant.
- What We Make
- 26 power cable accessory products across six categories covering every layer of a termination joint and busbar system
- Who We Serve
- Distribution utilities EPC contractors switchgear OEMs renewable developers and industrial maintenance teams
- What Problem We Solve
- Cable fails where the screen is cut where cores separate and where the jacket is damaged. We seal insulate and grade every one of those points
- Why Customers Choose Us
- 24 years of radiation cross linking with our own compounds IEC 60502-4 test evidence and direct engineer contact on WhatsApp
How a Termination Is Built
Every Layer in a Medium Voltage Termination Comes from One Factory
A cable does not fail in the middle of a run. It fails where the screen is cut back where the cores separate and where the jacket is broken. Each of those points needs a different material and we make all of them.

Inside the Factory in Dalian
Every photograph below is our own plant. Nothing in the electrical path of a UPM accessory is subcontracted.
The Dalian Plant
Compounding extrusion irradiation expansion molding and test all sit on one site in Shihe Industrial Park Dalian. Nothing in the electrical path of a UPM accessory is subcontracted.
Extrusion and Processing
Extrusion lines running single wall dual wall and co extruded product. Line side stations let an operator check wall thickness and concentricity without stopping the run.
Braiding and Winding
Braiding and winding lines feeding the sleeve and screen products. The same winding discipline is what lets us supply cable accessory tubing on spool rather than only in cut lengths.
Semi Finished Stock
Spooled semi finished product held between extrusion and expansion. Holding stock at this stage is how a made to order size still ships in 15 to 25 working days.
Finished Goods Warehouse
Packed and labelled finished goods staged for despatch. Every carton carries a batch record that traces back to the compound lot and the process parameters that made it.
Production Line
Watch the Line That Makes the Material
Radiation cross linking is what turns an ordinary polyolefin into a heat shrinkable one. It is also the step most accessory suppliers do not own. Our extrusion irradiation and expansion lines run under one roof which is why we can change a wall thickness or a shrink ratio without asking a third party.

Customer Feedback
How Overseas Customers Actually Talk to Us
We do not use contact forms. Every enquiry runs on WhatsApp or email directly with an engineer and these are the conversations that follow.
We had flashover on four outdoor terminations after the sandstorm season. Can you help before the next shutdown
Send a photo of one termination with a rule against it. If the surface is sound you can retrofit Y3 rain sheds without rebuilding anything
Photos sent. How many per phase
Six per phase for that pollution level. Quote and drawing on the way
Received. Order placed. Nothing has tripped since we fitted them
We need halogen free busbar insulation for a 36 kV cubicle. Data centre customer will not accept anything else
S1(n)-35 is the grade. Send the bar section and the joint detail and we will quote tube plus S1-B covers as one package
Drawing attached. Also need cut lengths so we do not waste bar stock
Cut to your lengths and labelled per position. 18 working days
Arrived labelled exactly as the drawing. Saved our assembly team two days
Our approved design specifies Raychem JSCR and HVOT. Are your parts a real equivalent
C102-10 for JSCR and C101 for HVOT. We will send dimensions and test data so your design authority can compare directly
Design authority approved the substitution last week
Good news. First production batch can ship in 10 working days
Confirmed. Price difference paid for the whole approval exercise
