faq
What is a Heat Shrink Straight-Through Joint?
It is an electrical accessory used to permanently connect two cable sections while restoring insulation, screen continuity and outer sheath protection.
What voltage is it suitable for?
The reference JTS1 product is designed for medium voltage systems up to 24 kV. Other manufacturers also offer heat-shrink straight-through joints for higher voltage classes, so the actual rating depends on the specific model.
Can it be used with aluminium conductors?
Yes, suitable configurations can be provided for aluminium conductors, subject to the connector and cable specifications.
Can it be used underground?
Yes. Heat-shrink straight-through joints are commonly used in underground cable systems, provided the selected model has the required sealing and environmental protection characteristics.
What information is needed to select the correct joint?
The key information includes rated voltage, conductor cross-section, cable insulation diameter, conductor material, cable construction, screen type and cable outer diameter
What is the typical lead time for orders?
Typical production lead times:
- Standard specifications (common sizes): 7-15 working days after order confirmation
- Custom specifications or special requirements: 15-25 working days
- Large volume orders: production schedule confirmed at time of order
We also maintain inventory of fast-moving standard sizes for immediate shipment. Transit time depends on destination port and shipping method. We can ship by sea (most cost-effective for large orders), air (urgent shipments), or rail (for Central Asian destinations).
