92×44mm Integral Plug-in VDIS with Panel Grounding Hole
92x44mm Grounding-Hole VDIS: This product is part of the indoor high-voltage presence indicating system (VPIS/VDIS) range for 3.6, 7.2, 12, 24 and 40.5 kV switchgear at 50/60 Hz. It uses low-power LED display components for low consumption, high stability and an LED service life of more than 100,000 hours. The panel grounding-hole design supports cabinets that require dedicated grounding on the front panel. When used with disconnectors, grounding switches and matching sensors, it supports voltage-status indication and anti-misoperation interlocking. Custom options can include primary voltage, operating power, sensor capacitance, panel cutout, alarm output and communication functions.

Product Details
Product Overview
The 92×44mm Grounding-Hole VDIS gives operators clear voltage presence indication in indoor medium-voltage switchgear. It works with 3.6kV, 7.2kV, 12kV, 24kV, and 40.5kV switchgear at 50/60Hz. Operators check the line, busbar, or cable side before switching, grounding, inspection, or maintenance. This quick status display supports safer daily operation. The product suits switchgear factories, ring main unit projects, compact substations, and OEM cabinet production.
Structure and Installation
The front panel includes a grounding hole for cabinets that need a dedicated ground point. Cabinet makers can mount the unit quickly on the front panel. Technicians can inspect or replace the device during routine service. The compact layout helps keep the cabinet panel neat. This design helps standardize assembly and reduce service time in batch production.
LED Display Performance
The device uses low-power LED display components. These LEDs offer low consumption, stable indication, and clear visual status. Their service life can exceed 100,000 hours. This long life helps reduce maintenance pressure during continuous operation. Operators can read the status quickly through the front panel.
Voltage Indication and Interlocking
The 92×44mm Grounding-Hole VDIS works with matching capacitive sensors, disconnectors, and grounding switches. The system shows live voltage status in the primary circuit. It also supports anti-misoperation interlocking. This function helps prevent incorrect grounding and unsafe access. The clear indication gives technicians an extra safety reference before operation.
Custom Options and Project Support
Manufacturers can configure primary voltage, operating power, sensor capacitance, panel cutout, alarm output, and communication functions. Product pages can include outline drawings, cutout diagrams, and rear wiring diagrams. Selection tables help engineers match sensors, circuits, and cabinet drawings. With a grounding-hole panel layout, the 92×44mm Grounding-Hole VDIS supports switchgear factories, contractors, and system integrators.
