Heat-shrink vs cold-shrink terminations — which to use?
Both families seal and insulate an MV cable end. Heat-shrink tubes are shrunk onto the prepared cable with a torch — economical, widely available, tolerant of awkward geometries, and the standard choice where crews already carry torch tooling. Cold-shrink bodies are pre-stretched on a spiral core and unwind onto the cable with no heat — faster to install, consistent in result, and preferred in confined spaces or where open flame is unwelcome. Silverstone Electric supplies heat-shrink cable accessories and cable terminations from Suzhou, China; the choice follows your crew's tooling and site rules.

Frequently asked
Which is faster to install?
Cold-shrink is generally faster per termination and less operator-dependent; heat-shrink is economical and familiar wherever torches are standard kit.
Are both for XLPE cable?
Yes — both families are applied to XLPE MV cable; confirm cable class and cross-section at RFQ.
Can we mix on one project?
Yes — many crews use cold-shrink where heat is restricted and heat-shrink elsewhere; both can ship in one package.
