B - Cable fastening• TOLMEGA products insure a continuous cable support system (CEI 61537).NOTICE . Basket trays : If data cables are not correctly fixed, theresult can be a deformation on every transversal wire mesh, 100 mm to 100 mm. Of course, this distortion is bad for the signal quality. We recommend to unroll cables instead of pulling it, do no twist anddo not overload.

• Direct wall fixing or horizontal wall fixing : Cables must not being damaged by their own weight.Between 2 cable ties, the minimum span is :> 0,4 m (conventional cables) > 0.75 m (screened cables).

• Horizontal or wall fixing applications : cable ties must be used for power cable (ejection risk in case of short-circuit)

• Insulated or non insulated mono conductors are not allowed in cable trays.

C - Equipotentiality• Connect cable trays to the ground of the installation in orderto increase equipotentiality.

Connect cable trays to the ground of the installation each 15 m. If the length of the routing < 15 m, connect the end of cable tray to the ground of the installation. Use TOLMEGA’S earthing fasteners.

Electromagnetic Compatibility (EMC)5

A - DefinitionElectromagnetic compatibility : Capacity of an appliance or a systemto work correctly in its electromagnetic environment without producing electromagnetic pollution.

Earthing:Earth : earth ground, OV potential reference.Earth plug: Conductor in direct contact with earth.Earthing and grounding must be separated:

• Earth network is connected to ensure the people protection.• Grounding is active against electromagnetic influence.

On site, these 2 networks are connected. This multiple link solves theproblem of high impedance of the HF (high frequency) earth conductor.

B - Level of electromagnetic pollutionProducts in compliance with IEC 61537 standardare, in current use, passive against electromagneticinfluences. (emission & immunity).The different levels of disturbance are defined :

Emissionsniveau

C - Reducing effects of cable trays2 types of reducing effects of cable trays :

• By grounding, the cable trays achieve a better equipotentiality of the installation. The currents created by field influences in cabletrays are cleared.

• Grounding connection reduces disturbance by generation of a reversed field.

D - EMC characterisationThere are two different ways to characterise the products :

• Characterisation of the reduction of the radiation (dB) according to the frequency.• Characterisation of the transfer impedance (Ohm)according to the frequency.

a)The first characterisation is not recommended : • There is no standard test report method about cable trays.• Reducing radiation effect depends on reference, but EMC references are not stable (according to connections, installation conditions, environment conditions,…)• So, results are not repetitive. They depend on test methods and conditions. It could be dangerous to extrapolate on site the reduction of radiation measured in insulated room.

b) Characterisation by transfer impedance is the way used by laboratories and cable manufacturers : • impedance is a intrinsic parameter of the cable trays, apart from conditions of use.• Measurement method is well known, repetitive and suitable. TOLMEGA uses this characterisation method.The lowest transfer impedance level is the highest reducing effect of cable trays.

Materials and finishes6

WHITE RUSTUnder what conditions does white rust appear ?Fast oxidization is needed , either under a heterogeneous film of water, or under permanent condensation (for example by differential aeration).This fast oxidization can be local or general. It is the precipitation ofbasic salts of zinc Zn (OH) 2. These basics salts are powdery, not veryadherent and provide no protection. However, they quickly combinewith components of the surrounding air to form a protective layer ofbasic zinc carbonate. The basic salts formed are not very soluble inwater and they accumulate in the surface patina until reaching a state ofbalance between their elimination in the form of soluble salts and theirgeneration by oxidisation of the metal.White rust has no effect on zinc coating lifetime.

A - Selection table

ZINC ON STEEL COATING

• G: HOT-DIP MILL GALVANIZED STEEL SHEET(EN 10327/ ASTM A653 / BS 2989)The galvanized steel sheet is obtained by immersing a previously-treatedsteel sheet in a bath of molten zinc at 450-460°C. The current grade of Z 275 NA is of a thickness of 18 µ per face, or 275 g/m2 per double face,normal zinc formation N, finishing grade A. Contrary to wide-spread belief, no corrosion is possible in sections of the metal when a galvanized metalsheet of current thickness is sheared or stamped. Iron is protectedthrough the battery phenomenon consisting of the Iron-ZINC ELECTROLYTIC system.

• HDG: HOT-DIP GALVANIZED AFTER FABRICATION(EN ISO 1461/ ASTM A123M / BS 729)After a surface treatment, the steel is immersed in a bath of molten zinc.This gives a zinc thickness ranging from 49 to 70 µ depending on thethickness of the metal sheet.

• ZINC +: COATING ON EZThis special zinc protection process allows a better corrosion resistance than G or EZ (saline spray test ISO 9227: 400 H). Appearance: silk finish. No droplets after drying.

• EZ: ELECTRO-ZINC GALVANISING (EN 12 329- EN 12 330 - NFA 91472/ ASTM B 633)Electrolytically, a zinc coating is deposited on the steel. The baths usedconsist of acid alkali solutions of zinc salts. The anodes are in zinc (generally to 99.99 % of purity) and the parts to coat, previously degreasedand cleaned, are connected to the cathode. After galvanizing, the parts are chromed to increase the protection.

• PG: CONTINUOUS HOT-DIP GALVANISED WIRE(EN 10244-2)The wire is continuous hot dip galvanized (220 g of zinc/m2).Then a wire drawing is processed in addition. For UNIFIL products, this is a very economic and high corrosion resistance proceeding.

• GM: Zn/AL coating1) GM process is made of very thin strips of zinc and aluminium into a mineral binder. This structural passivation allows an equivalent corrosion resistance than hot-dip galvanization (saline spray test ISO 9227: 1000 H).2) Chrome free coating according to ROHS.3) Applications: Bolting nuts in association with HDG products.

• ZM: High corrosion resistance zinc coatingZM process is an electrolytinc zinc coating and high corrosion finish.ZM is chrome free to ROHS. Allows an equivalent corrosion than HDG (saline spray test ISO 9227/1000 H). Applications: all products not available for HDG process. Appeerance: light blue bright.

* Sometimes EZ or SS bolting is used. If EZ bolting, bolts and nuts willbe corroded in some years.If SS bolting, cable trays will be corroded. Bolts and nuts can be removedin this case. This effect will be increased in outdoor applications.

B - Electrolytic corrosionElectrolytic corrosion is defined as a process of accelerated corrosion resulting of an electric current between two metals coupled in an electrolyticenvironment .Below the red line, the metal is being attacked.The joined metal undergoes no galvanic corrosion but, on the contrary, enjoysan effect of galvanic protection. Electrolytic corrosion is very important whenchoosing the assembly bolts and certain accessories different from the cableway support. (See table)
