Instructions for transport,handing,storage of the drums and laying of the cables


Technical Information



The cables, whether they are armoured or unarmoured, are manufactured with high quality materials allowing long storage, handling, transport and unreeling subject to the following recommendations.

Before acceptance of a shipment, all reels must be ins- pected. Any sign of damage should be noticed to the carrier (broken flanges, damaged wrapping or lagging, interlocked flanges, broken reels …).


Transport and handling:

The wooden drums must be always carried vertically. They must be fixed and properly chocked with care on the vehicle, on the wagon and on the ship, in order to avoid any exterior damages.

The unloading and the different handling will be done carefully with lifting equipments.

In case of handling with a crane, an axle is used in cros- sing the drum centre, lifted from both ends by two slings. It must have a length equal, at least, to the width of the drum. It prevents the lifting cable or chain from pressing against the reel flanges.

In case of handling with a forklift truck, the drum is laid vertically with care on the forks.

Rolling direction:

When a reel is rolled from one point to another, it must be rolled “only” in the direction shown by arrows as printed on the reel.


Cables can be stored, with site temperature limits :

-15°C to +60°C. The cables drums must be appropria- tely wedged and stored in a vertical position (never laid on flange) on a flat, dry and solid ground. They must be protected to avoid any mechanical risk and exterior shocks.

Laying of the cables:

Laying temperature:

Installation shall be postponed if the temperature is lower than - 5 °C. Below this temperature, cables shall be stored in a room where temperature is higher than 10°C at least 24 hours before unreeling. Cables shall be unreeled as soon as they are removed from the room and the usual bending radius should be increased as possible.

Bending radius:

During the unreeling, the bending radius shall be, at least, “twice the static bending radius (as specified in our technical data sheets)”.

The original wooden lags have to be kept until the cable unreeling to ensure a good protection of the cable. The both ends of the cable (inner and outer ends) have to be watertight in order to avoid penetration of water or humidity inside the cable. Thermo retractable polyethylene caps must be fixed on both ends.

Pulling strength:

The pulling strengths applied directly to the copper or aluminium cores of the cables should not exceed:

5 daN/mm2 of cross section for copper conductors

3 daN/mm2 of cross section for aluminium conductors.

The pulling must be regular without shock and conti- nuously checked by a dynamometer (especially in case of using a winch).


Cables unreeling:

The drum shall be settled on jacks by using a spindle through the central hole of the drum. The unreeling speed shall be monitored at any moment.

The cables must be unreeled “only in the opposite direc- tion indicated by the arrow“ printed on the flange of the drum (“do not unreel the cable in the same direction of the arrow”). While unreeling, the cables shall not be twisted, waved or buckled.
