2 1. General The Israel Electric Corporation LIMITED (I.E.C) requires stainless metal splice closure for jointing, branching and distribution optical fiber cables, to provide protection for fusion splices. 2. Scope 2.1. The Offeror shall submit technical documentation and type tests reports, according to the requirements of the Specification The Supplier shall be responsible for delivery of all items and will perform On the Job Training with the first 2 Installations of the closures at I.E.C. sites. 3. The proposal Over all Structure The proposal s structure must match the specification's structure, point for point. For example, section 9.1 of the proposal will consist of the response to section 9.1 of the specification, section 9.2 will respond to section 9.2, etc. When there is no response for a section of the specification, the corresponding section of the proposal should be labeled no response, so that the numbering scheme for subsequent sections will continue to match. The proposal shall be written clearly and in detailed. The proposal shall be written in English or Hebrew language solely. Responses are compulsory. It is compulsory to respond to every section, to match the structure within each section, and to match the detail within each section. The offeror is entitled to add further remarks and suggestions in an additional section entitled Other and numbered x.97 or x.y.97 as appropriate to the hierarchical level. If the response is lengthy, it is recommended to use an appendix at the end of the proposal. For example, section 10.1 of the proposal would refer to appendix 10.1, and that appendix would complete the details of the proposed solution regarding data security. Similarly, section 10.2 would refer to appendix 10.2 for additional details of the proposed database, etc. It is extremely important to use appendices, in order to keep the body of the proposal simple and easy to read. Technical and promotional materials should be attached as appendices to the relevant sections and referenced as described above.

3 4. Technical Documentation 4.1. General All data and descriptive material shall be in English or in Hebrew.

The closure shall be suitable for installation and operation in overhead electric lines, and attached to very high voltage towers poles (up to 400 KVAC) Minimum lifetime expectancy of the closure shall be 25 years 5.8. Functional Requirements Fast and easy installation of closure is required.

4 The closure installation and Opening /Closing of the closure shall be without any need of special or dedicated tools The closure will provide 4 circular entries (minimum). Each entry shall fit cables diameters range: mm The closure shall support jointing the following optical cables: - OPGW (Slotted core, Stranded loose tubes, Central aluminum buffer tube) - underground cable - ADSS - WRAP All cables entries shall be placed at the bottom side of the closure The closure will be re-enterable for expansion or repair. After reentering the closure's degree of protection will remain IP67 (at least). After closure sealing, adding of any a cable shall be fast and easy, without disrupting the already installed cables or disassemble existing cable in existing entries The closure shall be equipped with a padlock shackle diameter 8 mm. The required padlock's manufacturer and type will be according to IEC Instructions. The supplier will be obligated to provide these specifics padlocks (which are being used in IEC) The surfaces of the closure must be designed to resist cutting, abrasion or severe bending of the fibers or the tubes or the cables. Edges of the surfaces of the closures need to be polished and processed in a manner that prevents injury \ installer safety violation The closure shall contain 3 splice organizers (minimum). Each splice organizer: - 48 splices each (minimum, single stack) - Internal width: 12 cm (minimum) Total available splices per closure: 192 (minimum) The closure shall allow storing minimum of 2.6 meter spare for the original 8 tubes (3mm in diameter). The loose tubes shall be stored safely and protected from any damage can be occurred during installation, hanging and post hanging period The internal mounting bracket for the organizer shall allow modular and flexible mounting of organizer modules Maximum weight (without: mounting bracket, padlock): 23 kg.

5 Fiber safety Inserting or removing fibers and working with the splice organizers shall maintain and not harm fibers vitality, safety and integrity Inserting or removing a splice organizers from the closure or performing repetitive splicing in the same splice organizer or repeated opening and closing of the closure must be easy and convenient to the installer and maintainer. Repeating these actions will not harm existing services and will not harm the integrity of the closure IEC may reject an offer when the installation or the maintenance is complicated or does not provide protection for the fibers from damage or bending. 6.
