Field-proven 25kV 250A Straight Connector Brings Reliable Separable Connection for Medium-Voltage Cable Projects

When you’re working on medium-voltage power distribution, field installers always value one thing above many others: simple, tough, waterproof separable connectors that hold up in harsh real-world conditions. Our 25kV 250A load-break straight connector is built exactly for that kind of site demand.

Many site operators run into headaches: tight installation space, mixed indoor-outdoor layouts, or locations exposed to moisture and flood risks. This straight-type cable connector solves those practical pain-points. Paired with matching bushings or plugs, it delivers fully-screened, submersible separable joints. It can run reliably even under water or other rough site environments.

One really handy design touch is its built-in capacitive test point. Technicians can check circuit status on-site directly, or hook up fault indicators when you need condition monitoring. Another big plus: no minimum phase-to-phase clearance requirement. That gives engineers much more freedom when laying out compact switchgear cabinets or cable distribution boxes. Mounting is flexible too – vertical, horizontal, any-angle installation is all acceptable.

Rated continuous current hits 250A, with 300A overload support lasting up to 8 hours. It works with XLPE, EPR polymeric cables, fits copper or aluminum conductors ranging from 25 mm² up to 120 mm². This unit is compliant with GB/T 12706.4-2002 and IEC 60502.4-2005 standards. Electrical performance covers 125 kV impulse withstand, 54 kV AC withstand voltage for 5-minute test, 12.5 kA 1-second short-circuit withstand capability.

It is widely used to link polymeric power cables with transformers, switchgears and other MV equipment, for both indoor and outdoor deployment. Every complete kit comes with cable lugs, installation tool, cleaning paper, silicone lubricant, installation manual and quality certificate, so field crews get everything they need for on-site assembly.

For utility contractors, EPC firms and distributors sourcing medium-voltage separable cable accessories, this 25 kV straight connector is a solid, field-ready option for your upcoming projects.
