The essential feature of the internal construction is thehomogeneous resin and glass fibre bond over thecomplete insulated surface of the ZnO varistor elements.The arrester module has good conductivity even whenhigh cantilever loads are applied and provides a uniformdielectric at the insulated surface of the ZnO elements.
• No air gap therefore no internal ionisation
• Light weight compared to porcelain
• Ease of installation
• Non shattering housing
• Vandal proof

The series parallel construction comprises individualsurge arrester modules rated between 30 and 45kVinterconnected by means of corona free aluminium alloycross arm.
Each surge arrester module is completely impervious tothe ingress of moisture and utilises the high mechanicalstrength properties of the ZnO varistors bonded bycured resin impregnated glass fibre.
The seismic performance of the 500kV arrester has beenproven in two leading test facilities. Bonneville PowerUSA performed at Portland State University and NELEast Kilbride UK.
• No air gap therefore no internal ionisation• Light weight compared to porcelain• Ease of installation• Non shattering housing• Optimised voltage stress grading eliminates need to
oversize stress grading ring, therefore the compactseries parallel can be installed in tight spaces withoutinfringing electrical or surge safety clearances.
• The diameter of the series parallel design has beencalculated to reduce the radial field stress to aminimum, even under adverse environmentalconditions.

The PSRB surge arrester is available for applications upto 220kV systems.
The design utilises a housing construction, which is aresin and glass fibre strengthening sleeve over mouldedwith Silicone Rubber outer insulating housing fitted withaluminium flanges.
High cantilever mechanical strength is achieved on thisdesign with the internal assembly similar to that of theporcelain Housed Surge Arrester.
The design has been tested to IEC and demonstrates a63kA short circuit performance.
Routine tests are carried out to show that themanufacturing conforms to the current internationalstandard.

Spark Gap Type SPG4/12
The SPG4 Spark Gap is designed for use with tractioncircuits to provide virtually instantaneous protection ofboth equipment and personnel from power systemfaults. The unit also provides protection against lightning generated voltages which would otherwisecause damage to signalling and cable circuits.
The SPG4 is constructed in stainless steel of ruggeddesign allowing the SPG to be installed in harshenvironments such as track side locations withoutadditional weather protection.
Suitable for use on circuits where standing/inducedvoltages do not exceed 110v RMS.
Fast operation – Typical 5 microseconds with 11kA faultcurrent.
Internal spark gap module unit easily replaced after faultcurrent operation.
Fail safe feature ensures safety to personnel andequipment.
Service proven performance.
High internal impedance with low capacitance – does notinterfere with track signalling circuits.

Airfield Lighting Box Type 2DCAFL4
There are few places more exposed to direct lightningstrikes than an airfield. In such situations lightningstrikes within the vicinity of the airfield can result inpermanent damage to electrical equipment.
Airfield lighting circuits are particularly vulnerable asthe associated cable networks present an attractive lowimpedance path for lightning surge currents to earth.The result of a nearby lightning strike can bepermanent damage to the control circuits unless asuitable lightning arrester is fitted to the lightingcontrol equipment.
The Lightning Arrester Type 2DCAFL4 is designed toprotect airfield lighting control equipment from theeffects of direct or indirect lightning strikes.
The arrester is provided with two metal oxide activeelements which are connected in parallel with thesupply cables. Installation requires only the cutting ofthe supply cables at a convenient place close to thecontrol equipment and connection of the arrester to agood electrical earth.
Arrester 2DCAFL4 can be fitted to new equipment butis primarily designed to be quickly installed on existingcircuits.

Surge CountersType SC12 & SC13
The Bowthorpe EMP range of SurgeArrester monitoring instruments arefully tested for use with anymanufacturers surge arrester. TheSC12 is a Surge Counter only, whilstthe SC13 provides the additionalmeasurement of total leakagecurrent. The analogue instrumentprovides a means of monitoring thecurrent through the arrester and theleakage current over the surface ofthe arrester housing. Significantchanges after installation mayindicate a deterioration in thearrester or a build up of surfacecontamination.These instruments, which require noauxiliary supply, are designed forinstallation in the earth connectionsof a single surge arrester oralternatively the SC12 may be usedwith the common earth of a threephase set. Fully weatherproofed andsealed for life they are housed in aone piece gravity die cast aluminiumcase coated to enhance its alreadyhigh degree of resistance to surfacecorrosion. The glass viewing windowis sealed in place, using a siliconrubber adhesive, and a desiccator isenclosed to ensure any residualmoisture trapped during sealing isabsorbed for the service life of thecounter. Mounting is effected bymeans of an integrally cast lug at the
rear of the case providing a singleclearance hole for the galvanisedsteel M12 bolt supplied.
The SC12 and SC13 are serviceproven and require no specialmaintenance or servicing apart fromgeneral cleaning of the glassviewing window and the mouldedepoxy resin line terminal bushing.
