About Us

Switchgear & Logic Controls

We are manufacturers and suppliers of precision Electrical Control Panels, VFD and PLC Automation panels. Every assembly is built using advanced process techniques, high-grade electrical and electronic components and in-house sheet metal fabrication — so the panel that leaves our works is dimensionally accurate, fully tested and ready for site.

What We Build

Our Specialities

Seven core product lines covering power distribution, motor control, drives, automation and high-current bus duct systems.

Power Distribution

Power Control Centre (PCC)

Floor-mounted, front-operated assemblies for main incoming power distribution. Built from CRCA sheet steel with a fully rated busbar system, ACB/MCCB feeders and metering, they form the backbone of the plant's LT distribution network.

Short-circuit withstand rated busbar arrangement
Single front / double front configurations
Complete metering, protection and annunciation

Motor Control

Motor Control Centre (MCC)

Compartmentalised fixed or draw-out modules that centralise the switching and protection of every motor on the plant. Each feeder is individually isolated so maintenance on one drive never interrupts the rest.

DOL, star-delta, soft-start and reversing feeders
Overload relays, ammeters and indication per module
Door interlocks for safe operator access

AC drive / VFD panel manufactured by SLC — 03

Variable Speed

AC Drive Panels

Variable frequency drive panels engineered around Siemens and equivalent AC/DC drives for precise speed and torque control. On pumps, fans and conveyors they cut energy consumption sharply while giving smooth, shock-free starting.

Drive-rated protection, filters and forced ventilation
Bypass and auto/manual changeover schemes
Configured, loaded and tested in-house before dispatch

Industrial Automation

PLC Automation

Turnkey PLC and SCADA panels built on Siemens SIMATIC hardware with HMI operator interfaces. As a Siemens System House we handle logic development, wiring, testing and commissioning under one roof.

Process sequencing, interlocking and safety logic
HMI / SCADA screens with remote monitoring
Site commissioning and operator training support

Automatic Power Factor Controller (APFC) panel by SLC — 05

Energy Savings

Automatic Power Factor Controllers (APFC)

Microprocessor-controlled panels that switch capacitor banks in steps to hold power factor close to unity as plant load varies. The result is lower reactive demand, released transformer capacity and an end to utility power-factor penalties.

Automatic stepped capacitor switching
Detuned reactors for harmonic-rich loads
Thermal protection and forced cooling

View Detail

Boiler House

Boiler ID/FD Fan Automation Panel

Dedicated drive and control panels for induced and forced draught fans. Furnace-pressure feedback drives the fan speed automatically, holding combustion stable and cutting the auxiliary power that damper-only control wastes.

VFD-based draught control with pressure feedback
Interlocked ID/FD sequencing and trip logic
Significant auxiliary power savings over damper control

Bus duct / busbar trunking system by SLC — 07

Power Transmission

Bus Ducting

Sandwich and non-sandwich bus duct systems in aluminium and copper for high-current, low-loss power transmission between transformer, PCC and load centres — manufactured on our own busbar processing machines and high-voltage tested before dispatch.

Aluminium and copper conductor options
Straight lengths, elbows, tees and tap-off boxes
HV and megger tested to specification

Mild Steel

Cable Tray

High-quality cable tray systems designed for safe, organized, and efficient routing of power, control, and instrumentation cables in industrial and commercial installations.

Type: Perforated / Solid Type
Width: 50 mm to 600 mm
Height: 25 mm to 150 mm

Our Quality Standards

Quality is checked at every stage, not just at the end. Incoming components are inspected against approved makes, fabrication is verified for dimensional accuracy, and every completed panel goes through electrical testing before it is cleared for dispatch.

This is what keeps our panels reliable in continuous-process plants where an unplanned shutdown is simply not an option.

Every panel is HV tested and megger tested, with test reports supplied on dispatch.
