In the period of last few years, the increase of telephone-usersand density of ducts surrounding cities which are endangeredon easy damage, forces the manufacturers of telecommunicationlinks to work out and use ducts under the earth-surface.Together with the increase of transferring wider frequencyband, it appeared that there are some difficulties with providingappropriate quality of transmission with using copperwires. Wider pass bands in fast networks, like Gbit Ethernetor ATM, means necessity of assistance the copper wires withcomplicated electronic systems. That is the reason why fibreoptics became alternative solution to copper wires.
Not mentioning creation of brand-new networks, one of thebiggest tasks for telecommunication network is protection ofalready made investments and re-usage of the biggest possiblepart of already existing cable-networks. This possibility isgiven by access systems. Access systems enable gradual changingdistributive copper wires with fibre optics. This solutionallows using existing exchange lines not only for transmissiontelephone and ISDN services, but also for transmission 2Mb/sflux with using digital exchange line technology.
The technology of access exchange guarantees updating existingtransmission network with usage of valuable electronicequipment. In order to lower the costs of modernisation, themost common solution is joining old part of installation (copperwires) with new one (fibre optic cables) in outdoor accesscabinets (like SZD).
The main task of outdoor access cabinet is full protection ofinstalled equipment. The cabinet fulfils the requirements ofprotection against negative influence of environment (rainand snow falls, sun, dust etc) and vandalism. Another veryimportant task of SZD cabinets is providing specified climaticconditions which depend on installed equipment.
The construction of SZD cabinet enables optional arrangementof inside equipment. It makes possible to use SZD cabinetsnot only in access systems, but also in each case wherethe protection of outdoor equipment working in extremeconditions is very important. SZD cabinets produced by ZPASNEThave been already used in telecommunication industry,on ships, platforms, stamping press and intermediate pumpinggas stations, heat and power stations, power industryplants, refineries, cement plants, for protection of machineryfor outdoor lightening operating etc.
