2 INTRODUCTION Gulf Cable and Electrical Industries Company K.S.C. (Gulf Cable) is the only domestic manufacturer and exporter power cables, control cables, telecounication cables and overhead conductors in Kuwait. We were established in March 1975 and have been listed on the Kuwait Stock Exchange since Our manufacturing operations coenced in We embarked upon a massive restoration our plant & it's facilities during the early 90's when state--the-art machinery and testing equipment were acquired. Thereafter, new machines are recurrently being introduced to enhance our production capacity and product range. The new machines and equipment have numerous built-in functions and features assuring precision and consistency the highest standard. On a regular basis, we develop new products and enhance our existing ones. At Gulf Cable we pay utmost attention to product quality, and to ensure this, we have adapted a comprehensive Quality Assurance System that complies with international standards. Quality has always been our top priority and meeting customer's expectations has been our prime objective. The very basis on which we have earned the confidence our clientele. At Gulf Cable we follow stringent quality standards which go beyond stipulatations international specifications, rendering long term performance and reliability to our products during their service life. At Gulf Cable we always aim for the best. When most the cable manufacturers in the region settled for ISO: 9002, we stand out with ISO 9001, which recognizes our ability for Design and Development as well. We are also acknowledged by the Kuwait Quality Mark issued by the Ministry Coerce and Industries.

3 PRODUCT RANGE I We at Gulf Cable always aim for the best. While most the Cable Manufacturers in Gulf and Middle East region settled for ISO 9002, we stand out with ISO 9001 which recognizes our ability for Design & Development as well. As a philosophy, our coitment to customers does not end with a sale. We also fer a host related services before and after the sale. These include, Application engineering service for selection appropriate product best suiting the end use. An extensive range cables, single core wires, flexible cords bare & insulated conductors manufactured to stringent Quality Standards going beyond international specifications. Design and Development products tailored to meet specific requirements the application. To help the customers understand the product intricacies and its performance levels. NOTE 1: THE TABULATIONS ON SUBSEQUENT PAGES FURNISH OVERALL DIMENSIONS, NET & GROSS WEIGHTS AND DRUM DIMENSIONS. PLEASE NOTE THAT THESE ARE "APPROXIMATE" VALUES. THEY HAVE BEEN FURNISHED FOR GENERAL GUIDELINES AND INTENDED TO BE USED FOR THUMB RULE ESTIMATIONS/FREIGHT CALCULATIONS. NOTE 2: THE FOLLOWING LIST TABULATES ONLY THE "STANDARD" PRODUCTS.
