Superior Reliable Insulation

Our Epoxy System is the 3rd generation with own formulation. The class H-180°C standard epoxy coating provides 100% waterproofing and high mechanical strength. It has been tested in accordance with IEC 61439-1 and IEC 61439-6.

Advantages of using epoxy coating as insulations:

  • Designed to withstand glitch and spikes in electrical system
  • Designed to cater for expansion and contraction during peak and off-peak hours
  • Capable of withstanding heat shock
  • High reliability under static conditions
  • High mechanical strength against impact
  • High thermal conductivity
  • Water and chemical resistant

Other Insulation Types

Besides epoxy insulation, we also provide other classes of insulation as below:

  • Class B – It consists of two layers of Mylar (Polyester Film) which resists temperature up to 130°C.
  • Fire Rated – It consists of 1 layer of Mylar (Polyester Film) and 2 layers of Mica (mineral silicate sheet) which resist temperature up to 900°C.
Joint System

In order to overcome extreme rugged conditions at site, the new Busbar Trunking System joint has been designed precisely and manufactured using the highest quality of materials to minimize all possible problems and enhance system performance.

This special design provides outstanding features as follows:

  • Incorporates a 5mm thermal expansion and movement at every point.
  • Allow ±15mm of lateral adjustment (total 30mm) to correct site measurement inaccuracy.
  • Able to tilt an angle of ±5° (total 10° along a single axis).
  • Bolt and nuts can be stainless steel, galvanized or chromed black high tensile steel.
  • Degree of protection of IP40-IP66.
  • Easy installation and removal at any joint in a run without disturbing the two adjacent Busbar Trunking System sections.
  • Water/chemical resistance BMC insulation plates.

All our products are high density and conductivity. Copper conductor has minimum purity of 99.95% with conductivity of >100% IACS while aluminium has minimum purity of 99.7% with conductivity>61% IACS. It is fabricated through a sophisticated thermal compression process which involves application of tremendous heat under high pressure. It can be tinned or silver-plated with epoxy powder coated as insulation giving 100% water and chemical resistance. Optional specifications can be designed and fabricated to customer requirement.

Advantages of using our conductor:

  • High electrical conductivity
  • Low impurity
  • Excellent fatigue resistance
  • High thermal conductivity
  • High mechanical strength
  • Outstanding corrosion resistant
Tap-off Units

Tap-off unit with moulded case circuit breaker (MCCB) or fused-switch breakers of various current ratings are available to cater for most installations. Maximum 5 tap-off units per side can be installed, total 10 nos per length of 3m busbar subject to the size of MCCBs.

  • All tap-off unit are designed with interlocking safety features to prevent removal when tap-off unit in ‘On’ position.
  • When tap-off unit cover is open, automatically, MCCB cannot be turned ‘On’
