Our Products

HV & MV Switchgear

MV Switchgear constitutes the units designed for a rated voltage of 12 kV and current range 630A to 1250A. Switchgear insulation designed to withstand rated voltage is also subjected to over-voltage due to lighting and breaker operation transients. On the basis of the conditions, the Installation of switchgear is designed and assembled for outdoor and indoor service. Compatible for mass production, convenient operation, and transportation handling, the weight of the equipment is kept as low as feasible. Trizone HT, MV Switchgear is equipped with Vacuum Circuit Breaker (VCB) or Load Break Switch (LBS) to meet individual specifications which comply with IEC, BS, VDE, ANSI standards. Circuit Breaker & other elements which are imported from Japan, USA, Germany, France, & others EU countries.

Trizone LV Switchgear is furnished with ACB, MCCB, MCB to fulfill requirements that concur with IEC Standard. Switchgear with low voltage constitutes the units designed for a rated voltage of 500V and current range up to 6300A, Rated Current in copper busbar 1000A/1500A/2000A/2500A/3000A, Power Frequency Withstand Voltage 3 KV/1 min, Rated Frequency 50Hz.

PFI/Reactive Power Compensation (RPC) Plant

It is inevitable to set up a PFI/RPC plant for any electrical system where the inductive load is confronted to reduce the electricity bills considerably. PFI Plant is designed and assembled up to 11 kV system which corresponds to IEC/VDE standards & regulations and maintained its protections according to the client’s system requirements. Trizone’s PFI/RPC improves the efficiency of load, increases the voltage, and saves the energy cost from monthly consumption. Our skilled engineers always guide the users on their exact reactive power compensation needs.

Lightning Arrester & Drop Out Fuse

Lightning arresters can be considered as the first-ever components of a substation. The main function of this equipment is to protect the components of the substation from passing high voltage as well as limiting the amplitude and duration of the current’s flow. It is generally connected between phase conductor & ground. These components divert the flow of current to the ground and therefore protect the system’s conductor as well as insulation from harm.

Drop Out Fuses are protection devices that protect networks and equipment from current surges and overloads. An overcurrent will melt the fuse element in the carrier disconnecting the line or equipment. They also provide network isolation points when manually operated with a hot stick.

Bus-Bar Trunking System

Busbar Trunking System is a system of distributing electric power using copper or aluminum busbar with suitable enclosures and a good amount of protection to prevent the cables from getting damaged due to foreign bodies. Busbars are now becoming irreplaceable simply because of the convenience and safety factors. While using traditional cables, the cost of cabling and trunking and the time taken for installation is much higher than busbars as well.

Motor Control Centre

The motor control center is designed up to 11 kV according to IEC/VDE standards. It ensures exact safety measures for manual or automatic operation for control & automatic protection of the motors which are installed in the industry with built-in safety alarm. These are made in different types as per the client’s choice.


Diesel Generator

A Diesel generator is a device that converts motive power into electrical power. It is reliable for offices, business centers, factories, residential buildings for the smooth and easy power supply which keeps your valuable machines & appliances on and active. Mechanical sources include steam turbines, gas turbines, water turbines, internal combustion engines that have been used to produce electricity. We provide a large selection of diesel generators ranging from 5KVA to 3MW for domestic purposes as well as industrial use.


Gas Generator

A gas generator is a device that converts mechanical power into electrical power. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, and even hand cranks that have been used to produce electrical energy.


An automatic voltage regulator provides continuous power conditioning and the broadest range of protection available. It guards against voltage fluctuations that can wreak havoc on your electrical load equipment, costing you money in damages and lost productivity. Safely bridge all voltage anomalies and ensure maximum uptime and motor life for valuable production equipment. This automatic voltage regulator utilizes solid-state microprocessor-based regulation to adjust voltage, with a multi-shield computer grade transformer and filter to remove transients and noise.
