1. Introduction

Ruggedized Outdoor Marshalling Kiosks for High-Voltage Substations

Engineered as the critical field termination point between HV switchyard equipment and your control room. The JXF series provides weatherproof signal marshalling, local monitoring, and auxiliary power distribution in a fully enclosed, welded steel cabinet built for harsh outdoor environments.

✅ IP65 Weatherproof Rating | ✅ IEC60439 Compliant | ✅ -40°C to +55°C Operating Range | ✅ 690V / 630A Rated

2. Product Overview: Why This Kiosk?

The JXF Marshalling Kiosk is not a standard distribution panel—it is a purpose-built substation interface enclosure. Designed explicitly for outdoor installation on concrete pads within high-voltage switchyards, it serves three critical functions:

Field Cable Termination Hub: Organizes and terminates control, protection, and instrumentation cables from transformers, circuit breakers, and isolators before routing to the control room.

Local Operation & Monitoring Station: Provides front-panel ammeters, voltmeters, selector switches, and status indicators for safe on-site verification without entering the main control building.

Auxiliary Power Distribution: Delivers rated 3-phase AC power (50/60Hz, up to 690V, 630A) for motor starting, lighting, and heater circuits directly at the equipment location.

Built with a fully welded profile assembly and corrosion-resistant coating, the JXF withstands UV exposure, rain, dust, temperature extremes, and mechanical impact—ensuring decades of reliable service in unattended outdoor locations.

4. Critical Service Conditions (Outdoor Validated)

⚠️ Designed Exclusively for Outdoor Substation Environments

Temperature Range: Operates reliably from -40°C to +55°C, accounting for direct solar heating that can add 10–15°C above ambient air temperature. Internal space heater prevents condensation during cold/humid conditions.

Humidity & Condensation: Rated for 100% RH with condensation. Sealed gaskets and internal heaters prevent moisture ingress and tracking/flashover risks.

Installation Altitude: Suitable up to 2,000m above sea level.

Environmental Exposure: Resistant to UV radiation, industrial pollution, salt mist (coastal sites), wind loading, and wildlife intrusion. Rodent/bird-proof cable entry glands included.

Mechanical Stability: Must be installed on a reinforced concrete foundation with anchor bolts. Designed to withstand wind loads per local utility standards. Not suitable for wall mounting.

Vibration & Impact: Welded construction resists vibration from nearby HV equipment and accidental impact. No violent shock exposure permitted.

5. Why Choose the JXF for Your Substation?

Eliminate Indoor-Rated Enclosures Outdoors: Avoid costly failures from water ingress, UV degradation, and condensation. The JXF is validated for direct outdoor exposure.

Reduce Control Room Cable Clutter: Terminate field cables locally, minimizing long runs back to the control building and improving signal integrity for protection relays.

Enable Safe Local Operations: Front-panel instruments and controls allow technicians to verify circuit status and perform switching operations at the equipment location, reducing response time during faults.

Utility-Grade Compliance: Meets IEC60439 and relevant grid operator specifications for outdoor LV switchgear and marshalling equipment, ensuring acceptance during technical evaluation.

Customizable Wiring Architecture: Flexible terminal block layouts, surge protection options, and grounding configurations adapt to complex substation designs without redesigning the enclosure.
