Raccords à manchon thermorétractables BHT
BHT heat shrinkable butt connectors join conductors with a copper crimp sleeve and adhesive-lined PE heat shrink insulation.
- Four models for catalog conductor ranges from 0.3–0.5 to 4.0–6.0 mm².
- 3:1 shrink ratio; shrink begins at 80 °C and full recovery is listed at 130 °C.
- Listed operating temperature: −55 to +125 °C.
- Select by conductor range, copper sleeve diameter and length, finished diameter, and color.
Aperçu
BHT Heat Shrinkable Butt Connectors combine a copper crimp sleeve with an adhesive-lined PE heat shrink tube for inline conductor splices. The catalog lists four sizes covering conductor cross-sections from 0.3 to 6.0 mm². The heat shrink layer is intended to insulate the joint and help protect it from moisture and corrosion.
Caractéristiques
- Adhesive-lined heat shrink tube for sealing around the splice.
- 3:1 shrink ratio across the BHT series.
- Copper crimp sleeve with model-specific diameter, length and wall thickness.
- Four catalog sizes identified by wire range and insulation color.

Selection Guide
Choose the model by the conductor cross-section and check its copper sleeve dimensions against the intended wire and crimp tooling. Specify the complete BHT model code and quantity when requesting a quote.
