faq
What is a Cast Resin Straight-Through Joint?
A Cast Resin Straight-Through Joint is a cable accessory used to connect two sections of cable and restore electrical insulation and environmental protection around the splice.
Can it be used with copper and aluminium conductors?
Yes. Suitable versions can be used with compression or screw connectors for copper and aluminium conductors
Can the joint be installed underground?
Yes. The reference product is specified for indoor, outdoor, underground, water and installation-duct applications.
What cable insulation materials are compatible?
Compatible cable insulation types include PVC, PE, XLPE and EPR, subject to the selected joint size and cable configuration.
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).
