MM Power Plus Busway systems (Macau)

MM Powerplus Busway offers a wide range of products designed to suit almost any location. It is available with either copper or aluminium conductors in the range from 400 to 6000 Amps. Larger sizes up to 10,000+ Amps can be designed to suit special requirements.

The use of finned aluminium casing is an enhanced cooling concept. It allows heat generated by the conductor bars to be dissipated more efficiently than the larger steel casings of conventional busway systems. The effective size of the earth is typically 2-3 times the size of the phase conductor, and this provides a better capacity earthing medium for the whole electricity supply system.
   
The unique single bar design allows a more compact system installation to be obtained, such that it can fit with every environment. Its compact size and narrow width enable installation in confined spaces, thus requiring less room to be allocated to electrical riser services. In the higher amperages it usually requires less than half the space of other busway systems, or similarly rated cable formations. It requires less installation time, avoiding complications arising from parallel bar arrangements. The compact size and inherent low impedance make it the most versatile system available for feeder and rising distribution mains application.

The sandwich construction, using Class B insulation material (Polyester Mylar 130 DegC) between conductor bars, means internal smoke and fire barriers are not required. The busway run is available in weatherproof type (IP54) and outdoor type (IP66) configuration.

Joints are made by simply sliding together and tightening the clamping bolts progressively to the torque specified. This ensures equal load sharing, and even contact area, on multi-bolt joints – a feature not available with shear-head bolts.

ASCO ATS & Surge Divertors (USA)

Series 300 Power Transfer Switches
The SERIES 300 is listed to UL 1008 standard for Transfer Switch Equipment and CSA standard C22.2 for automatic transfer switches.
Meets NFPA 110 for Emergency & Standby Power Systems & the National Electrical Code (NEC) Articles 700, 701 & 702.
30 through 3000 amps in a compact design.
Available to 600 VAC, single or three phase.
True double-throw operation: The single solenoid design is inherently inter locked and prevents contacts from stopping between sources or from being in contact with both sources at the same time.

Lifasa (Spain)

LIFASA capacitors are produced with the more advanced and modern techniques, result of a wide know-how in reactive fields as well as very strict testing and D+I+i.
Reactive power LV compensation capacitors
 
Lifasa power capacitors are dry capacitors, and consequently ecologic. It doesn't exist the possibility of liquid loses.
 
Elements are totally encapsulated in resin thermally-hardened , with high dielectric properties, without impregnation.
 
Elements are connected together to obtain the desired reactive power, and they are assembled into boxes or metallic cans. Empty spaces are fulfilled with a non flammable inert material from mineral composition. Each element is protected individually.
 
Cylindrical capacitors : single-phase ELEFP, three-phase POLT and three-phase POLB.
 
Prismatic capacitors : single-phase FMI, compact three-phase MFB, standard FMD/FMC/FMY, six terminals FMT/FMS and   reinforced FMR.
 
Condensadores equipados : with fuses CPF, with breakers CPM, with fuses and contactors CAB and module MOD.
