Toptech has access to specialty lighting capacitors such as those used in stadium lighting situations and hi-bay lighting towers in general, both in quantity and singly. The correct choice of capacitor for many situations may appear simple but if there is any doubt as to the suitability (or not) of a particular capacitor for a particular installation, it is almost guaranteed that the experienced engineers at kVArCorrect can recommend the correct solution. This may be from one of our preferred power quality capacitor suppliers, as detailed below; from our preferred motor run capacitors supplier, ELCO; or from another brand to better suit the situation.

Busway Systems
The merging of Linkk Busway Systems of Malaysia with Megaduct busduct trunking systems has provided incredible flexibility in the solutions available. Since 1992, Megaduct have been designing and manufacturing the Lego-like alternative to cables that is busway. With products used in many projects in Australia, Malaysia, Singapore, and across the world, the Kuala Lumpur based Megaduct factory has the utmost of testing facilities, quality assurance procedures, production processes, and design methods. All Megaduct Busway Systems are light weight, low impedance, non-ventilated, naturally cooled, and totally enclosed within the steel or aluminium housing. Advantages of using Megaduct busway:
|
✓ Higher efficiency in power transmission and distribution
✓ Lower cost of installation ✓ Compact and suitable for small spaces ✓ Extremely flexible in design, manufacture, and installation ✓ Easier maintenance ✓ Higher reliability ✓ Longer life span ✓ Very easy to expand onto the system in future ✓ Extremely high short circuit current ratings ✓ High electrical and thermal conductivity, with low impurities ✓ High mechanical strength, excellent fatigue resistance, and outstanding corrosion resistance Technical information and Product Options: ✓ Various System Voltages, with further options being available upon special request: ✓ 3P3W and 3P3W+50%E ✓ 3P4W, 3P4W+50%E and 3P4W+100%E ✓ 3P4W(50%N) and 3P4W(50%N)+50%E ✓ 3P4W(200%N) and 3P4W(200%N)+50%E ✓ All systems tested and certified by ASTA to comply with BS 5486; IEC 61439, 60439, 60331, 60529 ✓ Feeders, plug-ins, joints, tap off units, bends, and all manner of pieces available ✓ Various IP ratings available, from IP20 up to IP68 across various products |

Megaduct has the option of using highly conductive Copper as a core material, or the more affordable option of Aluminium. Because of their material selection, design methods, and manufacturing processes, using Aluminium still provides excellent conductivity suitable for a busduct system.
✓ Copper bar with high purity for high conductivity >99.95% ✓ Aluminium bar with low impedance and high conductivity >61% Whilst Megaduct favours Epoxy as an insulator, they also produce other options in their systems. The Epoxy is applied to the conductor bar as a coating, in a special process that is unique to Megaduct. The factory employs a 100% test rate on the coating quality, and any failure to this stringent test means the entire bar is rejected. With these strict quality procedures and the costly consequences of a failure, it follows that this Megaduct process is highly accurate and effective - there are very few failures.
✓ Epoxy - Megaduct own unique formulation, 3rd Generation, Class H ✓ Class H - temperatures up to 180⁰C ✓ Tested to IEC 439-2 and BS 5486 ✓ Water and chemical resistant ✓ Withstands electrical spikes and heat shock ✓ High thermal conductivity ✓ Designed specifically to expand and contract during different loads and conditions ✓ High reliability under static conditions ✓ High mechanical strength and impact strength ✓ Mylar - Polyester Film, Class B-130⁰C ✓ Class B - temperatures up to 130⁰C ✓ Two layers ✓ Nomex/Mylar - Meta Aromid Paper, Class F1-150⁰C ✓ Class F1 - temperatures up to 150⁰C ✓ One inner layer of Nomex, with two outer layers of Mylar Megaduct has spent considerable time on the design of their busway joints to allow them to overcome rugged site conditions. Features of their one-bolt-bridge joints include:
✓ One Bolt Bridge Joint System - simple! ✓ Incredibly easy installation and removal of any joint without disturbing adjacent busduct sections ✓ Tolerance of 5mm thermal expansion/movement at every joint ✓ Allows +/- 15mm of lateral adjustment (corrects any issues with site measurement inaccuracy) ✓ Tilt angles of +/- 5⁰ ✓ Bolts/Nuts available in stainless steel, galvanised or chromed black high tensile steel ✓ DMC/SMC insulation plates to enhance water/chemical resistance ✓ Optional shear off twin headed bolts to required torque of 70Nm Tap-Off Units, or Plug-In Units, are the points at which the busway system branches off to allow the user to access the power. These can have non-fused circuit breakers (MCCB) or fused-switch breakers, of various current ratings. In a three metre length of two faced busduct, there can be up to five tap-off units per face, depending on the size of the MCCBs. These units are all safety interlocked to not only prevent active device removal, but also shut the MCCB down when the unit's door/cover is open.

Arguably the biggest cause of failure of non-LED commercial/industrial lights is capacitor failure. Indeed, using the incorrect capacitor, even if it is the one originally purchased with the fitting, can be a huge safety risk through fire and even explosion. Specialty lighting capacitors such as those used in stadium lighting situations and hi-bay lighting towers in general can be recommended through Toptech's connection with kVArCorrect.
In addition to this, Toptech carries the experience of working in the Australasian Emergency Lighting industry for a number of years, being knowledgeable about exits, emergencies, lighting layouts, LED lighting in general, DALI control, and other monitoring systems. Toptech has been involved in writing, amending, advising on, and responding to tender documentation and project specifications across the Electrical industry in both Australia and New Zealand for many years. We are able to assist with existing specification documentation by answering any questions, highlighting any contradictions, recommending solutions, or explaining any aspect that falls under our areas of expertise. We are also able to assist the creation of all new specifications, ensuring the features you require are specified clearly and concisely.
Combining Toptech's history with electrical documentation with Megaduct's team of design engineers, we are able to advise on a busway systems. The Megaduct installation is relatively quick and easy, but there will be Toptech engineers available throughout installation and commissioning. This is because there are a number of critical measurements and decisions that need to be monitored.
Toptech is interested in the entire process of your operation, rather than just the product we provide. If you have any questions about where we think our products could assist your site or business, we are always happy to have a chat!
