JCSI

When reliability is non-negotiable, you need a splice that’s proven to meet the highest standards. JCS 35 is NKT’s new IEEE-qualified cold-shrink splice for cables up to 35 kV, engineered for dependable performance in demanding North American networks.

· IEEE 404-qualified: Every splice is factory-tested for partial discharge and AC withstand, meeting the highest North American standards.

· Advanced stress control: Factory-molded stress cones and integrated Faraday cage for stable electrical performance under modern switching conditions.

· High-performance silicone insulation: Delivers high dielectric strength, low tension set, and excellent recovery at low temperatures.

· Semi-conductive protection system: Thick conductive tube over the semicon layer ensures electrical continuity and protects against handling damage.

· Compact joint body: Fits a wide range of cable sizes while keeping installation space to a minimum.

· Shear-bolt connector: Market-proven, dual-rated (Al/Cu), and easy to install with standard tools – no crimping or special dies required.

· Exceptional sealing system: Internal and external seals resist moisture ingress, supporting long-term insulation integrity even in underground and high-humidity environments.

· Shelf life: Minimum 4 years at 68°F (20°C), supporting flexible storage and logistics.

· Optional heat-shrink rejacketing: For shield break applications we , an optional heat‑shrink rejacketing system is available.

· Supports standard and specialized installations: Designed for utility networks and the installers who build and maintain them across the US and Canada.
