GLOW WIRE TESTING Burning behavior of compounded thermoplastics is not just a material characteristic. It's also dependent on the shape and wall thickness of the application. In Europe, flammability is tested using Glow Wire Tests according to IEC 695-2-1 and/or the Needle Flame test according to IEC 695-2-2.

Components or parts may, under faulty conditions or overload conditions, attain a temperature such that they are unduly affected or such that they will ignite parts in the nearby area. The Glow Wire Test simulates thermal stresses which may be produced by such sources of heat or ignition, for example the glowing elements of overloaded resistors, in order to assess by simulation technique the fire hazard.

Test procedure Sample: Thinnest wall thickness of the completed application. Pre-treatment: 24 hours at 23 degrees C at 50% RH. Temperatures of glow wire: 550, 650, 750 850 or 960 degrees C depending on the relevant specification). Force: 1 Newton. Contact time: 30 seconds.

Requirements The specimen is considering to have withstood the Glow Wire Test if one of the following

applies: There is no flame and no glowing on the sample. Flames or glowing of the sample extinguish within 30 seconds after removal of the glow

wire, and if the cotton or the paper underlay doesn't ignite or burn.

Performance criteria The criteria for failure under integrity and insulation for partitions as specified in the standard are given below. In the absence of a specific test for sealing system, the same criteria were used except where stated.

Integrity is defined in terms of failure by sustained flaming cotton pad and gap gauges as follows:

Sustained flaming when sustained flaming for not less than 10s on the unexposed face occurs

Cotton pad when cracks, gap or fissures allow flames or hot gases to cause flaming or glowing of a cotton fiber pad.

Gap gauges when a 25 mm-diameter gap gauge can penetrate through a gap into the furnace; or when a 6mm-diameter gap gauge can penetrate through a gap into the furnace and be moved in the gap for a distance of at 150mm.

Insulation: Failure is deemed to occur;

a) When the mean unexposed face temperature increases by more than 140 deg C above initial value;

b) When the temperature recorded at any position on the unexposed face is in excess of 180 deg C above the initial mean unexposed face temperature;

c) When integrity failure occurs.

*The mean temperature rise was not considered applicable to a test of this nature.

Test Standard: IEC 60439-2 3rd Edition

Test Clauses: 8.2.2 & 8.2.2

Test Title: Verification of temperature-rise limit & verification of electrical properties for plug in unit

Test material: Usual IEC standard required one tap off to be tested but in actual condition it’s should run with at least 3 nos of tap off unit.

Performance criteria

The object under test successively consists of a flange, a joint a first straight length, another joint and a second straight length. The tap-off units IBD types 3P/100A, 3P/200A and 3P/400A are all connected to the tap-off points of the second straight length. The configuration is detailed in the drawing. The total length of the bus bar trunking system is 6.75 m and placed horizontally (edge wise) on supports approx. 1 m above the floor.

The 50Hz three phase current source was per phase connected by four black painted copper bars of 100 X 5 mm 2 cross sectional area, length 3 meters to the incoming terminals of the flange and loaded with 2500A. The starpoint was mounted directly to the end of the second straight length of bus bar. The tap-off units 3P/100A, 3P/200A, and 3P/400A are connected with 35, 95, and 240 mm2 cables of 3 meters length and loaded with respectively 100A, 185A and 390A.

The temperature-rise were measured by means of thermocouples, including the ambient temperature. The location of the thermocouples is indicated in the test report. The current in each phase is kept constant until thermal equilibrium is reached. The recorded temperature-rise values shown in the report.

The Overlapping Systemandards ur “UNIQUE” Overlapping Joint system which gives almost 100% joint overlap thus reduce heating

in the joint. Translite MF Bus Duct patented Overlapping joint system offers incredible stability, durability and ease of operation. Multiple conductors, insulators and duct joiners are

tightened with a MF Nut which serves as an electrical and mechanical joint. The other important components incorporated in our joint system are the Belleville Washer, High Tension Bolts, Fitting Stopper and Captive Hardware. The Belleville Washer disperses the pressure on overlapping conductors and absorbs thermal expansion and contraction. The High Tension Bolts with heat proof insulation are pre-fit into the joint covers, which prevent any removal and alignment of bolts during jointing. The Fitting Stoppers are provided at the duct joiner for regulating the conductor overlapping during jointing. Last but not least, the captive hardware stops the turning of the joint bolts for ease of tightening.

The “MF” in our bus duct stands for “Maintenance Free” which comes from 3 main parts not likewise the other brand considered the BOLT & NUT that gives the maintenance free. Below its show the maintenance free in our bus duct comes because of the 3 parts which;

No Items Description Remark

1

Contact surface treatment

Copper conductor contact surface require special treatment for stable and long-lasting operation. Normal silver or tin coating copper contact surface, which is the most common solution, will cause peeling or ‘blister’ during long hours of contact. Hence, these plated surfaces are structurally weak and most vulnerable to friction. Translite MF Bus Duct evolves a new solution by applying Special Alloy coating with excellent adhesion bondage properties to contact surfaces. The Alloy treatment coated surface can withstand long hours of cyclical thermal heating process without any peelings.

Maintenance Free Nut

Translite MF Bus Duct tightens all joints with the maintenace free (MF) nuts. The MF nut has a continuous inner thread and a torque limited neck. Thus, a little torque remains when the neck is broken, which locks automatically and will never loosen. The torque limited neck will break at a torque of 1200 kgf/cm.

The tightening of the nut can be confirmed visually by observing the slip indication line carved on the nut surface.

Belleville Washer

Our own Belleville Washer acts as tension absorber to compensate for expansion and contraction as experienced by all metals as they heat up or cool, in addition to the structure aging of the bars.

Vertical Components

Translite MF Bus Duct is the only bus duct use a single piece copper for the vertical components. Rather than others do a welding to joint 2 pcs copper bars together. Please refer below

The Overlapping System

Make the bus duct inline and just

need to push through until it reaches the stopper. A consistent

joint surface area is always achieved with the use of the

stopper in the simple joint system, which provides an automatic guard

guidance to ensure the installer does not push too far in or out

Our overlapping joint works as a male and female

joint, where you just need to push right up to the stopper.

cf

By using the special socket

just tight as normal till the MF nut will break

Make sure the inner portion is clean from any foreign materials and Use the joint cover to closed

and tighten with bolts and nut given.

Once everything is completed finally do

the visual check before put the confirm

label.

Insulation Properties ith its inherent properties of strong dielectric strength and wide temperature range (-70 to + 150 °C), polyester film was the perfect choice for insulating our bus duct. We apply 4 layers with 125 micron layers each, in total 500 micron which can withstood 155KV of dielectric strength.

The 4 overlapping layers resulting the airtight seal that is sufficient to guard against any moisture. It has mechanical properties for elongation of 130% to cater for copper temperature rise expansion which is maximum 24%. Normal application can be use up to 150o Celsius class F insulation & melting point at 263o Celsius.

Polyester insulation, besides being functionally effective, is more reliable than Epoxy insulation given many technical advantages such as those mentioned above.

Other properties of Polyester such as its high dielectric and tensile strengths, resistance to chemicals, low moisture absorption, etc, also make it a good choice of insulation material to be used in bus duct system.
