26/35KV Heat Shrinkable Power Cable Accessories
26/35KV Heat Shrinkable Power Cable Accessories is built from Polyolefin / Silicone rubber. It ships expanded and recovers to a tight, conforming fit once you apply heat (hot-air gun, 150–250 °C). On the shelf it is held to working range -50℃~+125℃, rated for 26/35KV. Buyers spec it for HV cable termination and jointing — the typical call is a sized part that stays put through vibration, thermal cycling and field handling. Below is the spec table, the size matrix we keep in stock, and the selection notes our engineering team uses when a purchaser sends a cable or component drawing.

What it is and how it recovers
26/35KV Heat Shrinkable Power Cable Accessories starts as an expanded tube. The expansion is locked in by cross-linking, so it holds the large diameter until heat is applied and it recovers toward its extruded size. Because the body is Polyolefin / Silicone rubber, the recovered wall keeps its dielectric strength and mechanical protection after cooling — it does not relax back. For procurement this matters: the part you receive is reusable on the bench, but once installed it stays put for the life of the assembly.

Primary applications: HV cable termination and jointing.
How to select the right size
Specifying 26/35KV Heat Shrinkable Power Cable Accessories is mostly about matching three numbers to the part you are covering:
- Supplied vs. recovered diameter. The sleeve must slide over the largest feature (connector, lug, splice) and recover snugly on the smallest. Send us the largest and smallest OD and we return the exact part number.
- Temperature class. The continuous range is -50℃~+125℃. If the assembly sees brief excursions beyond that, tell us — we will flag a high-temp grade instead of letting the wall soften in service.
- Voltage rating. This item is rated 26/35KV. Do not substitute a low-voltage sleeve on a medium-voltage joint; the wall thickness and tracking resistance are different by design.
- Wall and adhesive. Thin wall for tight harness bundles; medium/thick wall or adhesive-lined (dual-wall) where you need environmental sealing or abrasion resistance. We keep both in stock.
Frequently asked questions
What is 26/35KV Heat Shrinkable Power Cable Accessories made of, and how is it different from cheap PVC tubing?
It is built from Polyolefin / Silicone rubber, a cross-linked polyolefin that recovers to a tight, permanent fit after heating (hot-air gun, 150–250 °C). Unlike non-cross-linked PVC, it keeps dielectric strength and mechanical protection after recovery and does not relax.
Does it survive the temperatures my application sees (-50℃~+125℃)?
The continuous range is -50℃~+125℃. If your assembly sees brief excursions beyond that, tell us the fluid and temperature and we flag a high-temp or fluoropolymer grade instead of letting the wall soften in service.
How do I pick the right supplied and recovered diameter?
Choose supplied ID at least 2–3× the largest object (connector, lug, splice) so it slides on, then confirm recovered ID grips it. With a 3:1 ratio one sleeve covers both a bare conductor and a bulky connector; size up one step rather than forcing a tight fit.
What voltage class is it rated for?
This item is rated 26/35KV. Do not substitute a low-voltage sleeve on a higher-voltage joint — wall thickness and tracking resistance differ by design. For medium voltage, use our dedicated cable-accessory kits.
What flame / environmental certifications does it carry?
Compliance is IEC 60502 (flame class and RoHS/halogen status depend on grade). Certificates are issued per batch; tell us your target market and we align the filing. Available colours include black / standard.
When would I choose dual-wall adhesive instead of this single-wall tube?
Single-wall seals by physical fit; choose dual-wall (adhesive-lined) when you need environmental/water sealing, abrasion resistance or to fill irregular gaps. Send the cable OD, voltage class and environment and we return a sized recommendation with stock code.
