BASEC has issued a public warning notice about certain cables which have been sold into the UK market.
The cables are not BASEC approved and do not carry the BASEC mark.
The cables are multi-core PVC sheathed XLPE insulated steel wire armoured cables, of type BS 5467, in various sizes that are commonly used for low voltage power distribution.
BASEC testing of these cables has indicated a number of serious faults including excessive conductor resistance and excessive armour resistance.  The effective safe conductor size of the cables is up to two standard sizes smaller than that marked on the cables, which may result in overloading.  The armour resistance may result in ineffective earthing.

The British Standards Institute (BSI) has withdrawn the standard for instrumentation cable BS 5308:1986 Instrumentation cables parts 1 and 2, however because of the extent of the worldwide recognition and demand for these types there is a new publication - PAS 5308-1:2009 Control and Instrumentation cables.  Part 1: for polyethylene insulated cables and Part 2: for PVC insulated cables.
These “Publicly Available Specifications” available from BSI are endorsed by the BCA (British Cable Association) and the ECA (Electrical Contractors Association) and we will be manufacturing in accordance with the new documents.

high voltage cables up to 220 kV

While investigating new cables for power transport, we have realized a superconductor prototype and the accessories necessary for its installation.
Superconductivity is the elimination of the electrical resistance in the flow of current. A highly innovative technology applied also to electrical infrastructure for power generators and transportation of electricity. The various applications of superconductors include also power cables for energy distribuition.

TRATOS ARMAFLEX can be used in both dry and wet locations; in ventilated, non- ventilated and ladder type cable ducting, and is also suitable for direct burial.

Quantities start from as little as 100 mtr and up to 1500 mtr in a continuous length.  The interlocking armour is available in both Aluminium and Galvanised Steel upon request with a range of elements for use in automation, control, lighting, data, coaxial, fire resistant and power.  The sheathing materials available include Low Smoke Zero Halogen, MDPE and PVC; the interlocking armour is available in a range of sizes with an internal diameter of 8.5mm up to 33.50mm with other sizes available upon request.

Tratos Cavi has, for many years, been taking on the challenge of developing the right cables for extremely high speed container handling cranes. Below is a summary of Tratos’ on-site experiences in this field:

Critical Stress situations in high speed cranes: an analysis

The latest generation of container cranes (ARTG and RMG) are designed with ever increasing travel speeds, up to 300 m/min.

This poses an ongoing challenge to manufacturers both of cables and cable reels.

TRATOS approached this problem by looking back on their extensive experience in container ports worldwide. They noted that almost inevitably cables had to withstand a range of tensile loads during operation due to control systems being unable to suitably compensate for the forces involved during acceleration and braking. It is important to note that this exposure to a range of tensile loads is due in part to modern reel manufacture being designed to not expose the cable to a tensile load beyond certain limits defined by the manufacturer.
