Black C8

Wire Mesh Cable Tray

Pemsa has developed a high resistance coating for rejiband® wire mesh tray which provides an excellent resistance to corrosion in wet and aggressive environments.

High Corrosion Resistance

Demonstrated with more than 1000 hours in the neutral salt spray tests and obtained through a new manufacturing process that improves both the barrier effect against the aggressive media and the ability of self healing in damaged areas. With the result obtained in the neutral salt spray test, more than 850 hours, the corrosion resistance is classified as Class 8, according to Table 9 of the current standard BS EN 61537 trays.

BS EN 61537

This International Standard specifies requirements and tests for cable tray systems and cable ladder systems intended for the support and accommodation of cables and possibly other electrical equipment in electrical and/or communication systems installations. Where necessary, cable tray systems and cable ladder systems may be used for the division or arrangement of cables into groups.

Salt Spray Test Duration

Duration (h) Salt Spray Chamber Chamber Test – acc. ASTM-B117

Certified High Resistance
rejiband® BLACK C8 has obtained the AENOR N Marking (Spanish Association for Standardization and Certification) and the certification IECEE CB Scheme of IEC (International Electrotechnical Commission), garanting the Class C8 of resistance against corrosion, with more than 1000 hours on the Salt Spray Test.

BETTER FEATURES THAN HOT DIP GALVANISED

Hot dip galvanised normally ranges from between 45 to 70 microns mean coating thickness, so it should be Class 5, 6, or 7, having a lower corrosion resistance than BLACK C8.

Aesthetic appearance

The smooth finish is much more aesthetic than that of hot dip galvanised.

• No sharp edges or ends
• No irregularities or areas with reduced thickness
• Black colour provides excellent aesthetics which are suitable for decorative applications, commercial facilities, false ceilings, etc.

Electrical continuity

This coating maintains the electrical continuity of rejiband®, complying with the requirements of BS EN 61537 standard for cable tray system with electrical continuity characteristics. This feature allows bonding to other exposed conductive elements and, in case of a fault, the evacuation of electrical currents to the earth.

The most appropriate coating for Data Centres

BLACK C8 coating avoids the emergence of the phenomenon of Zinc Whiskers, or loosening of filaments of zinc, which can be a serious problem within the electronics of clean rooms in Data Processing Centres.

Increased capacity for selfhealing, or self-repairing, of the protective layer

The characteristics of self-healing, or self regeneration, on scratches, minor defects or in the cutting of the wire, are remarkably better than that of the zinc.

Excellent ductility

It is possible to bend the the tray without causing any damage to the finish. These features retain the properties of flexibility and the forming of accessories with rejiband®, bends, level changes, in any format.

Environmentally Friendly

The BLACK C8 coating is manufactured in a process which significantly reduces energy consumption and waste generation over other coatings which consume more resources like hot dip galvanised.

Full Range of brackets and accessories

rejiband® BLACK C8, product range includes a complete catalogue of accessories and supports,  providing a high corrosion resistance and a better visual aspect to the whole installation. This system offers the same corrosion resistance of Class C8 for everything, improving the performance of the system against aggressive environments and enhancing the performance of a hot dip galvanized finish, where accessories and brackets do not reach this classification. The system is complemented by the use of a black colour zinc spray that is suitable for the protection and aesthetic improvement of cut rods and possible damage caused during installation.

Fibre Optic Cable Blowing & Fill Ratio Calculations

• Guest Article by CBS Products

Blowing Fibre Cables

Fibre optic cable blowing isn’t a new technique for cable installation and, in fact, it has been in use since the late 1990’s. However, the cable blowing technique may be new to some installers. A range of CBS cable and fibre blowing machines help get the job done with ease for both the seasoned installer or the novice. In this article, we discuss one of the key parameters to a successful installation, the fill ratio.

JetStream Cable Blowing Machine

The Fill Ratio

The fill ratio can be calculated for a single fibre optic cable installed in an innerduct or microduct as:

d² ÷ D² < 65%

or

d²  < 65%
D²

The lowercase “d” stands for the outer diameter of the cable, while the uppercase “D” stands for innerduct’s inside diameter.

This means that when the cable outer diameter squared is divided by the innerduct inside diameter squared, the outcome should be less than 65% (or .65) for the most effective cable blowing.

Also, the fill ratio should not fall below 35%, as the cable may have more of a tendency to “kink” in the innerduct due to excessive turbulence.

Likewise, when the fill ratio is greater than 80% it becomes increasingly likely that there is insufficient space around the cable for the viscous drag principle of the air to act on the cable jacket.

The fill ratio is one of the parameters determining how far a fibre cable can be blown.

A larger fill ratio is preferred when the cables are relatively stiff and the duct run is straight.

A smaller fill ratio is typically preferred when there are multiple bends in the cable duct run, allowing more room in the innerduct for the cable to navigate the route.

The installer doesn’t specify the innerduct or the cable, but the installer can easily calculate the fill ratio and determine if the ratio is in the “sweet spot” or not.

A fill ratio out of range may explain why the cable installation didn’t proceed as planned.

ALADIN Individual Voltage Alarm With Headlamp For MV Overhead Lines 10-400kV

ALADIN | The Helmet Mounted Voltage Detector

Individual Voltage Alarm With Headlamp

• uploaded by Chris Dodds - Sales Marketing Manager Thorne & Derrick International

MV Medium Voltage Overhead Lines 10-400kV

P&B Weir together with Thorne & Derrick introduce an innovative new electrical safety product to the UK market – ALADIN is an individual voltage alarm with headlamp suitable for use with MV overhead lines in the voltage range of 10-400kV.

The electrical safety device is designed like a headlight to be attached on helmets or hard hats and complies with European Directives EN 61000-6-2 and EN 61000-6-4.

ALADIN is extensively used throughout the Rail, Renewable, Data Centre, Transmission & Distribution, Oil & Gas and Utility sectors for safe working around Medium & High Voltage Electrical Equipment, Switchgear, Substations, Cables & Overhead Lines with typical operating voltages 11kV 25kV 33kV 66kV 132kV 400kV.

Improved electrical safety levels for workers operating near live equipment

The personal electric field detector combined with professional headlamp provides the user with an audible safety alarm offering an additional level of safety for workers operating near energised equipment e.g during maintenance, rescue operations, painting and pruning.

The frequency of the audible alarm increases as the detected electric field increases. Example situations where the ALADIN provides improved electrical safety:

• Misunderstanding: the operator approaches a danger zone
• Voltage unexpected return. mistake during an operation on disconnected network
• Involuntary approach: quick move in direction of energised area during operation
• Diversion: the operator is distracted and moves towards a high potential energised conductor unconsciously

Calibration & Testing | The Aladin has an auto-test function but can also be checked by placing it in contact with an unshielded low voltage element such as a wall outlet or power cord.

ALADIN is suitable for outside and indoor medium voltage electrical equipment.

ALADIN is supplied in a cardboard box with a universal charger and micro USB cable, interface for fitting to a helmet, an elasticated band and four hooks, a reinforced protective case and users’ instructions.
