II. Financial Proposal -------------------------------------------------

LV Underground Cable Jointing COURSE OBJECTIVE: The range of voltage and capacity of power transmitted through cables has shown a steady increase over the years. Environmental concerns, aesthetic issues, lack of transmission corridors and difficulty in routing overhead lines in crowded human habitats are some of the reasons for the explosive growth of cable technology well into the extra high voltage range. Due to physical limits on cable lengths for manufacturing and packaging, joints in cable become inevitable, particularly in the context of the utility sector. The cables also need to be terminated at sending and receiving end equipment, a very wide variety of them, in utility as well as industry applications and these calls for appropriate cable termination accessories. Cable terminations and joints form the weakest link in any distribution system. At the completion of the course, participants will be able to:

Identity the different methods used in the test process Construction of electrical power cables, different types of cables for different voltage ratings and manufacturing aspects

Different types of connectors and connection methods Know and implement the safety rules & procedures for LV cables. Identify the components of L.V power cables. Measuring, cutting & stripping of LV cables. Use the tools &equipments for cable jointing. Straight Jointing and Termination of L.V cables. Identify the importance of cable jointing.

TARGET AUDIENCE: Anyone associated with power cable operation, maintenance, location and fault detection techniques. The workshop will also benefit those working in system design as well as site commissioning, maintenance and troubleshooting. Typical personnel who would benefit are:

Operations Personnel Electrical Maintenance Technicians and Supervisors Process Control Engineers Service Technicians Maintenance Personnel

II. Course Outline

COURSE DURATION: The course duration will be FIVE DAYS

10% Lectures in the Class 90% Practical Exercises Pre-Assessment & Post Assessment

COURSE LANGUAGE: The Presentation, supplied documents, and workshop exercises of the course are in English, however, based on the trainees desires, use of Bilingual (English and Arabic) for oral explanation is available. ASSESSMENT: Assessment is an integral part of instruction, as it determines whether or not the goals of the course are being met. This will be given to each and every attendee on: A. Before the Program (Pre-Assessment) Assessments being done before the Program is important to know into which level the attendees are. This will covered both theoretical and practical part which will be done by our Assessor. B. After the Program (Post Assessment) In the same way, assessment after the course is vital to measure how much the participants learned upon attending each courses. This will also be both measured through theoretical and practical assessments. The one who will pass the post Assessment will be qualified to do Electrical Switching Program for Electrical Equipment. CERTIFICATION: The Program is Certified includes Class discussions for the Theoretical Part, and Workshops for the Practical Part, Assessment will be done in the Last Day of the Training, the ones who will pass the Assessment will be getting the Competency Certificate from PTG and National Electric Center / Jordan . Others, who will not be able to pass, will get only attendance Certificate. COURSE OUTLINE THEORY
