Application Solutions

Heat shrink tubing production and inspection line at the Wellele manufacturing facility

Each route below names the one problem the application exists to solve and the factors that actually decide selection. Details, alternatives and caveats live on the solution pages.

Wire Harness & Cable Protection

Problem: harnesses rub through insulation and pick up damage where they pass panels, edges and moving parts.

Decide by: abrasion exposure, flex cycle count, temperature at the worst point, and whether the sleeve must go on after assembly.

Cable Joint & Splice Sealing

Problem: a joint is the weakest point in a cable run, water and partial discharge start there.

Decide by: voltage class, cable construction, joint system design, and whether a heat source is permitted at the installation site.

Busbar & Switchgear Insulation

Problem: exposed busbar phases in a cabinet are a touch-safety and phase-to-phase clearance problem.

Decide by: bar dimensions (width × thickness), voltage class, cabinet clearance, and whether installation happens before or after bus assembly.

800V Busbar Insulation

Problem: 800 V systems shrink clearances, so the insulation system has to be qualified as a system, not assumed from LV practice.

Decide by: system voltage and creepage/clearance targets, conductor geometry, bonding/deskewing needs, and the qualification evidence available per product.

ESS / Battery Storage Insulation

Problem: battery systems combine high DC voltage, tight pack layouts and fire-safety requirements that general-purpose tubing was never qualified against.

Decide by: cell/module geometry, thermal path, fire-safety spec (halogen-free where specified), and chemical compatibility with the pack coolant.

Automotive & EV

Problem: automotive harnesses combine heat zones, fluid exposure and vibration in packaging that leaves no room for oversize sleeving.

Decide by: temperature zone on the actual routing path, fluid contact, abrasion spec, and packaging space around the connector.

Industrial Equipment

Problem: motors, transformers and cabinets mix steady ambient heat with radiant and splash exposure that single-construction thinking misses.

Decide by: heat mode (ambient / contact / radiant / splash), dielectric requirement, and installation access on the machine.

Not sure which route fits?

Application deep-dives

Narrower pages than the seven routes above. Each one takes a single job, names the engineering constraint that decides it, lists the published ratings of the parts that fit, and sets out the inputs we need to size one.

Busbar Insulation Retrofitting

Insulating busbar in a cabinet that is already built: snap-on or heat-shrink, and the outage window that decides between them.

Substation Cable Terminations

Cold-shrink or heat-shrink termination and joint kits from 0.6/1 kV to 26/35 kV, and what the site permits.

Automotive Harness Sealing

Sealing ultrasonic weld and crimp splices against water travel on wet routes, with adhesive-lined tubing.

EV High-Voltage Protection

Abrasion, heat and colour on pack and HV harness runs, with component ratings kept separate from system approval.

Telecom Tower Weatherproofing

Sealing tower-top coax and antenna connectors with no flame and no power at height.

Motor & Transformer Leads

Hot motor and transformer leads: measured hot spot, assembly order, and varnish or oil compatibility.

Chemical-Resistant Fluoropolymer

PTFE, FEP and PFA for strong acids, solvents and hot caustic wash, including roller covers.

The product catalogue organizes the same parts by material, type, application and installation method, and the guides cover sizing and comparison decisions.
