faq
What is a Slip-On Straight-Through Cable Joint?
A Slip-On Straight-Through Cable Joint is a cable accessory used to permanently connect two cable sections while restoring electrical insulation, screen continuity and mechanical protection.
What is the advantage of slip-on technology?
Slip-on technology uses a pre-engineered joint body that can be installed directly onto the prepared cable, helping simplify installation and reduce assembly time.
Can it be used with copper and aluminium conductors?
Suitable configurations can be used with both copper and aluminium conductors, provided the connector and cable dimensions are compatible.
What voltage can this type of joint support?
The reference product is designed for systems up to 170 kV. Other slip-on joint products are available for lower voltage ranges
What information is required for product selection?
Customers should provide rated voltage, conductor cross-section, conductor material, cable insulation diameter, outer sheath diameter and screen configuration
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).
