The 2 common metals used for conductors in the electrical trade are: ___________ and ______________. Aluminium has become more prevalent for larger C.S.A. conductors as it is cheaper and lighter but more brittle than copper. Current/ Copper/ Aluminium Thermoplastic-sheathed cable (TPS) consists of an outer toughened sheath of polyvinyl chloride (PVC) (the thermoplastic element) covering one or more individual cables which are PVC insulated annealed copper conductors. It is a commonly used type of wiring for residential and light commercial construction in many countries. The flat version of the cable with two insulated conductors and an uninsulated earth conductor all within the outer sheath is referred to as twin and earth. In mainland Europe, a round equivalent is more common. Flat cables (or festoon cables) are made in PVC and Neoprene and are used as trailing cables for cranes, open filed conveyors and shelve service devices. Flat cables offer the advantages of extremely small bending radius’s, high flexibility and minimum wastage of space.

  • L Power Outage in Nigeria: History, Causes and Possible Solutions
    Journal of Energy Technologies and Policy www.iiste.org ISSN 2224-3232 (Paper) ISSN 2225-0573 (Online) Vol.2, No.6, 2012 Electrical Power outage in Nigeria: History, causes and possible solutions 1Arobieke Oluwole, 2Osafehinti Samuel, 3Oluwajobi Festus, 4Oni Olatunji Electrical Engineering Department, Rufus Giwa Polytechnic, Owo. *Email Corresponding Author [email protected] Abstract Power outages have assumed a very high embarrassing dimension in Nigeria. There are several areas of national life that power outage should never rear its ugly head but alas in Nigeria power outage for several days is commo n and could happen just anywhere – In 2009, the presidential palace was not spared and power outage became so frequent that ever since, the state house is powered 24 hours with generators. The last Junior World cup played in Nigeria really brought out some embarrassing moments when the whole pitch was thrown in darkness. The Muritala Mohammed Airport is not spared despite being the main gateway in the south into and out of this country. In the midst of this however, Nigeria's demand for energy and electrici ty is increasing rapidly and Nigeria has a 20 - 2020 vision (i.e. to become one of the twenty industrialized countries by year 2020). This paper covers 120 substations in Ondo State of Nigeria that can be described as fairly industrialised and well populat ed. The information available from these stations helps to describe a general situation facing the country as a whole. This article presents some solutions to these embarrassing moments. It is a paper designed to highlight some steps that can help achieve stable power supply in Nigeria.

  • CEC-12 [Rev-6] Page 1 of 6
    ELECTRICAL SAFETY Information Bulletin March 2014 CEC-12 [rev-6] Page 1 of 6 CANADIAN ELECTRICAL CODE SUBJECT: Section 12 – Wiring Methods Conductors General Insulation Thickness on Conductors Used in Ungrounded or Impedance Grounded Systems With the change in the conductor standards, RW90 conductor is now available with a voltage rating of 600V. The suitability of this conductor on 600V ungrounded and impedance grounded systems, where past practice has been to use 1000 V conductors, has been questioned. Electro-Federation C.A.N.A.D.A has issued a paper explaining that the insulation thickness on low voltage conductors is intended for mechanical strength as well as insulation value. Therefore, it is thicker than would be required for insulation value alone. Based on this, the wire and cable manufacturers have agreed that 600V RW90 rated cable is suitable for use on 600V ungrounded or impedance grounded systems. Rule 12-012 Underground Installations Mechanical Protection for Direct Buried Conductors The Appendix B Note on Rule 12-012 indicates that polyethylene water pipe in conformance with CSA Standard B137.1, Polyethylene Pipe for Cold Water Services is considered acceptable for mechanical protection of conductors or cables used for direct earth burial. Although acceptable for mechanical protection of conductors or cables installed underground, this material is not approved as a wiring material and should not be installed as a raceway inside buildings. Protection of Conductors and Cables A review of Rule 12-012(5) indicates that it is intended to apply to cables other than armoured cable, mineral-insulated cable and aluminum-sheathed cable.

    GAMBICA / REMA Technical Guide Variable Speed Drives & Motors Installation Guidelines for Power Drive Systems Fourth Edition : 2012 Installation Guide for Power Drive Systems Fourth Edition © GAMBICA/REMA 2012 FOREWORD This Technical Report has been produced to meet a demand for an authoritative guide on best practice for the installation of Power Drive Systems. It is the result of a study carried out by GAMBICA and REMA, taking note of well-established fundamental theory, technical papers, and carrying out specific investigations. The information given, while it can be applied to motors and inverters in general, is specific to current generation products of member companies. The Technical Report principally considers the aspects of safe mechanical and electrical installation and the avoidance of EMC problems. This report covers motors and inverters installed with a separate cabling system connecting the components together; it is not wholly applicable to inverters integrated into a motor design, which are now generally available up to 7.5 kW. The references together with a useful list of further reading are included in the final section of this report. SCOPE This report provides information on the basic principles that require to be considered when specifying, and installing, a power drive system. Supplies considered are low voltage up to 690 V a.c. The installation procedures detailed are specifically oriented to current United Kingdom practice. For the application of a power drive system incorporating Ex. motors, refer to the motor manufacturer for confirmation of their suitability and certification. SUMMARY Satisfactory operation of a drive system is dependent on a satisfactory installation.

  • Regulations for Electrical Installations - 1997 Edition
    REGULATIONS FOR ELECTRICAL INSTALLATIONS 2017 EDITION INTRODUCTION: This edition supersedes the REGULATIONS FOR ELECTRICAL INSTALLATIONS - 1997 EDITION. The Revised Edition incorporates the amendments and guidelines issued and posted on DEWA website from time to time. The objective of the regulation is to provide consumers, consultants, contractors, electrical engineers & technicians with general guide for design, installation, inspection and compliance with DEWA’s requirements for electric installations, in order to safeguard person and property from hazards arising from the use of electricity. The regulation however is not intended to substitute detailed specifications nor to serve as an instruction manual for untrained persons. It is essential that all consultants, contractors, electrical engineers & technicians study and abide by these regulations. This of course does not absolve the concerned parties from obtaining other necessary approvals from DEWA. References are generally made to the seventeenth edition of the IET (The Institution of Engineering and Technology) wiring regulation and International Electromechanical Commission (IEC) documents. Consideration has been given to the prevention of fire and shock hazards as well as proper operation and maintenance of wiring installation and equipment.
