•Emergency Change-Over Systems: Maintenance and repairs are conducted to ensure efficient and reliable emergency generator power in the event of power failures/ outages

• Testing: With advanced test equipment, we perform speed tests, ductor tests, pressure tests, infrared scanning and other functionality tests to ensure optimum and preventative solutions for equipment utilized.

• Substation Maintenance: We ensure that all major low voltage and medium voltage substations are well maintained at optimum levels at all times.

• Panel Upgrading: This entails upgrades to old and obsolete panels with modern versions to minimize down time in the event of failures.

• Mini-Subs: Maintained, testing and install new ring main unit

• Medium And Low Voltage Commissioning

• Automation and Control: This entails upgrade of the existing scada and new installation of Scada with RTU,

• Power lines and Cables: This entails installation of overhead lines on the high voltage system, cable installation and joints on the medium voltage to low voltage , also fault finding

Fire Suppression Systems are used to extinguish or prevent the spread of fires, Suppression systems use a combination of dr chemicals and/or wet agents to suppress equipment fires. This is achieved by releasing a gas or mixture of gasses into the air with a general aim of reducing hte amount of oxygen in the air that feed the flames.

AEC prides itself with the introduction of advanced fire suppression systems such as firekim.

1) How it works:

Automatic fire suppression system (Heat Detection type) reacting at specific temperature. When a specific temperature is reached in a small space, the capsule reacts to suppression the fire by cooling and suffocating. Novec1230, an excellent Fire extinguishing Agent, can be extinguishing in both electrical and deep-seated fire

2) Features:

Device configuration without power-loss and electronic-errors. Its light weight and smart design make it suitable for a wide range of applications for small space. Use of Novec 1230, a globally environmentally friendly fire extinguishing agent. No maintenance of general fire extinguishing system or fire extinguisher such as pressure is required. Excellent durability and moisture resistance. Can be customized to an optimized size within the legal design subspace (0.36 m³).

6) Expected effect

Cost savings due to restoration of switchboards and fire damage facilities / Cost savings due to fire-out. Rapid suppression of small space fires to prevent damage to main facilities. Reduction and prevention of social cost due to in substation fire.

AEC, as an extension to our medium and low voltage services, has extensively been involved with alternative energy solutions with a primary focus on solar energy and wind turbine systems. We have been developing and installing customized applications for sustainable and Eco-friendly power options with the aim of reducing the demand for traditional power sources with huge success

 

Products:

• Only products of superior quality conforming to relevant bureau of standards are utilized

• Accessories and spares for both solar and wind turbine systems are readily available and easily accessible.

 

Solar energy applications

• Keeping it simple and efficient, we are able to absorb and contain solar energy via solar panels. Utilizing inverters- the energy is then converted to suit various technical requirements. These generated voltages and amperage’s are channeled through a distribution board (DB) and energy then distributed accordingly to suit specific needs.

• Market segments are residential, industrial and infrastructure.

Wind turbine principal and applications

• In this process a mechanical propeller consisting of blades is forced to turn as wind gushes through it thereby activating a generator which produces energy.

• Energy can then be distributed through any desired grid.

• Applications would also include residential, industrial and infrastructure.

Aims & objectives

• To reduce total grid dependency

• To minimize downtime due to unplanned power outages

• To increase productivity

• To yield higher output profit margins

Our well-trained and highly skilled teams will provide you with the very best services, which include:
