CONDUCTORS Busbars Fabricated from high strength and high conductivity Copper or pure aluminum with a conductivity. Copper conductor or Aluminum conductor of 99.9% purity the conductor has fully rounded edges which make a smooth and easy connection between the busway.
ENCLOSURES Constructed with high strength extruded aluminum alloy profile and fully painted with epoxy compound power coating. Standard color code is RAL7032/7035 and special colors are available upon request.
INSULATION MATERIAL The phase and neutral bars are insulated with Class F polyester film insulation. The polyester film is applied by an automated fluidized bed process to ensure uniform thickness.
INGRESS OF PROTECTION (IP) The housing is totally enclosed with its fully insulated conductor to provide dust, water & insect protection, as according to IEC 60529 standards. Thus the degree of protection shall be min IP54 up to max. 56
Aluminum Alloy Enclosure
- PCK BUSWAY is constructed with high strength extruded aluminum profile and designed with additional cooling fins has resulted in the most compact busway system available.
- Compact size & lightweight
- High mechanical strength
- Corrosion resistant
- Superior heat dissipation
- Extremely low impedance ground path
- Superior ground conductivity
- Easy installation & maintenance
Compact Size
The additional cooling fins design allows the use of smaller busbar and offer a low impedance, small line loss, quick heat dissipation. PCK BUSWAY makes the system lighter and smaller than other conventional busway
- Compact size & lightweight
- High mechanical strength
- Corrosion resistant
- Superior heat dissipation
- Extremely low impedance ground path
- Superior ground conductivity
- Easy installation & maintenance
Ease of Installation
- PCK BUSWAY is using special joint kit which has two connecting plates and drastically decreased the contact resistance. Also, simple joint connection work can improve the installation process faster (Lower cost of installation) Double headed bolts can be used for proper tightening fastening by fastening the outer head until break off by wench (When the indicating disc falls off, the joint is properly tightened automatically) Large sized Belleville spring washers assure even pressure on contact. Each joint is designed to allow longitudinal busbar expansion or contraction by as much as ±10mm
Tap-off Units
Plug in box mechanically interlocked with the busway enclosure to prevent installation or removal while the MCCB is ‘ON’ position. It is equipped with an operating handle to control the switching mechanism. The plug in box makes positive ground connection to the enclosure before making contact to the phase conductors. The tap-off units from 600AF to 1200AF are fitted permanently to the connection points of the trunking units and cannot be fitted/removed while the system is live. Installation is only permissible when the system is isolated. The Plug in Box/Tap off Box is rated at IP42 as standard but customers can order IP55 as optional.
Superior Ground Conductivity
PCK BUSWAY is made from extruded aluminum which provides a very large grounding capacity because of the fins on the aluminum housing, the effective size of the grounding is typically 2~3 times the size of the active internal ground bar. If increasing ground capacity is required, we can provide additional 50% or 100% internal bus bar within the same busway enclosure.
200% Neutral Construction
PCK BUSWAY offers a fully rated 200% neutral bus option for busduct systems with non-linear loads. The additional neutral capacity prevents the overheating caused by zero sequence harmonic currents. The 200% neutral is manufactured using two 100% neutral conductors fully epoxy coated and combined via the joint kit to achieve the 200% capacity.
