8.16. Launcher lighting

8.16.1. Principle

The launcher is lit with floodlight type lights designed to illuminate great heights. These lightsare secured to the top of masts and pylons provided by the civil engineering work package,height to be defined by the lighting design documents. A platform will enable adjustment and maintenance once installed. The masts and bunkers are part of the civil engineering work package. However, thecontractors of the various work packages have to coordinate work to take into account allpossible constraints related to each work package.

8.16.2. Earth network

A ground ring earth network will be created at each mast or pylon anchoring spot.

13. OPTION 1: LAUNCHER LIGHTNING PROTECTION

Depending on the launcher lightning protection data and the induced or electromagnetic fields,which will be established by launcher development, the launcher lightning protection systemmay be reviewed and provided by a device other than the gantry. Currently, the protection system developed by ONERA on the ARIANE 5 base site comprises 4pylons with a wire stretched over the top and remote discharge of lightning current. Consequently, this system is an option and shall be designed and estimated as part of thisdescription. As part of this option 1, an additional option 1’ is requested.

13.1. Protection level As there is no permissible "lightning current" data for the launcher and for the induced orelectromagnetic field, the permissible " lightning current " of 5kA shall be taken into account forthe launcher. This "lightning current" value protects the launcher against lightning strikes of anintensity greater than 5 kA in 95% of cases according to worldwide statistics. The upper limit ofthe intensity of lightning strikes for which the launcher is protected is 200 kA (i.e. 1% of casesaccording to statistics). For an intensity greater than or equal to 5 kA, the striking distance defined according to theformula in NFC 17100: D=10x(I�2/3) is 29 meters, which is also the radius of the artificialsphere.

13.2. Principle To obtain the protection level defined above, the protection system associates two principles:

� the principle of the artificial sphere consisting in protecting the structure by aconducting cage of which the grid depends on the minimum intensity of the lightningto avoid, i.e. 58 m. This principle does not provide protection against nearby effects,

� the principle consists in discharging the lightning current to the ground by asymmetrical system.

The system based on the two principles provides a device:� for capture by stretched wires and rods installed on pylons,� discharging lightning strikes symmetrically to decrease induced or electromagnetic

fields at the launcher,� providing protection against direct high-intensity strikes, greater than 5 kA, without an

electromagnetic field induced in the system,� capable of collecting low intensity lightning currents, greater than 5kA, by pylons,� option 1’: capture by stretched wires and rods installed on isolating masts to obtain

remote discharge of lightning current. The entire set-up is supported by pylons.

4 sides (several wires if confirmed by the study),� anchoring of the four down conductors outside the bunker,� the radial system for pylons and discharges,� lightning counters with signal transfer on two diametrically opposite down conductors

according to the lightning counter description below,� posting of instructions close to the lightning protection system,� option 1’: isolating tube masts made of reinforced resin, height 12.5 meters,

diameter 0.9 m, with ladder (free clearance 0.65 m) to take into account theinstallation of discharge cables, capture rods, maintenance, etc.

� option 1’: symmetrical discharge of 4 down conductors separated by 100 metersfrom Almélec type pylon, section 228 mm².

Study and estimate for option 1’ shall be separate from option 1.

Technical specifications:� ST1: normal wind, speed 24 meters/second according to wind and snow rules,� ST2: maximum wind for launching: 23 meters/second, independent from height,� ST3: related to direct blast on the mast: launcher at 370 (AC) meters height: dynamic

pressure of blast assimilated to a 80 m/s wind (AC) according to direction inclined by° in relation to vertical, section involved, entire mast,

� ST4: related to direct blast on cable: ditto ST3 except for section involved, to take intoaccount: 20 meters horizontal projection with two cables covering the mast involved.
