[接上页] (L.N. 76 of 1982; L.N. 298 of 1982) Cap 406A reg 14 Other overhead lines Remarks: Adaptation amendments retroactively made - see 61 of 2000 s. 3 Save as above provided, overhead lines shall not be erected except in accordance with such regulations as the Chief Executive in Council may prescribe. (61 of 2000 s. 3) Cap 406A reg 15 Construction of receptacles for electric lines ELECTRIC LINES OTHER THAN OVERHEAD LINES All conduits, pipes, casings and street boxes used as receptacles for electric lines shall be constructed of durable material, and where laid under carriage-ways shall be of ample strength to prevent damage from heavy traffic, and reasonable means shall be taken by the company to prevent accumulation of gas in such receptacles. Cap 406A reg 16 Crossing pipes, etc. Where any electric line crosses, or is in proximity to, any metallic substance, special precautions shall be taken by the company against the possibility of any electrical charging of the metallic substance from the line or from any metal conduit, pipe or casing inclosing the line. Cap 406A reg 17 Electric continuity of metal conduits, etc., of high pressure line All metal conduits, pipes or casings containing any high pressure electric line shall be efficiently connected with earth, and shall be so jointed and connected across all street boxes and other openings as to make good electrical connection throughout their whole length. Cap 406A reg 18 Precautions to be taken when bare conductors are used (1) Where the conductors of electric lines placed in any conduit are not continuously covered with insulating material, they shall be secured in position, and no unfixed uninsulated material of a conducting nature shall be contained in the conduit. No such conductor shall be at a pressure exceeding 300 volts from earth. (2) Adequate precautions shall be taken to ensure that no accumulation of water shall take place in any part of the conduit and to prevent any dangerous access of moisture to the conductors or the insulators. (3) The insulators of any such electric line shall be so disposed that they can be readily inspected; but this requirement shall not apply to any such insulators which before 2 December 1921, were not required by any regulation then in force to be so capable of ready inspection. Cap 406A reg 19 High pressure lines laid above ground or in subways Every portion of any high pressure electric line placed above the surface of the ground, or in any subway not in the sole occupation of the company, shall be completely inclosed either in a tube of highly insulating material embedded in brickwork, masonry or cement-concrete, or in strong metal casing efficiently connected with earth. Cap 406A reg 20 Protection for surface of ground and electric lines Where any high pressure electric line is laid beneath the surface of the ground, efficient means shall be taken to render it impossible that the surface of the ground or any neighbouring electric line or conductor shall become charged by leakage from the high pressure electric line. Cap 406A reg 21 Completion and control of high pressure lines A high pressure electric line shall not, except with the consent of the Director of Electrical and Mechanical Services, be used for the supply of energy before it has been completely laid, properly jointed, examined and tested, or until it is in the sole charge of the company, and every such line shall during its use be in the sole charge of the company. (L.N. 76 of 1982; L.N. 298 of 1982) Cap 406A reg 22 Sub-stations SUB-STATIONS AND STREET BOXES Sub-stations shall be established in suitable places and shall be in the sole occupation and charge of the company. Sub-stations shall be erected above ground wherever possible, but where necessarily underground, due provision shall be made for ventilation and for drainage. Cap 406A reg 23 Street boxes In addition to the provisions contained in regulation 15 as to the construction of receptacles for electric lines, the following conditions shall be observed with respect to street boxes- (a) the covers of all street boxes shall be so secured that they cannot be opened except by means of a special appliance; (b) the covers of all street boxes containing high pressure apparatus other than cables shall be connected to strips of metal laid immediately underneath the street, and efficient means shall be taken to render it impossible that the covers or other exposed parts of these boxes, or any adjacent material forming the surface of the street, shall become electrically charged, whether by reason of leakage, defect or otherwise; (c) where street boxes are used as transformer chambers, reasonable means shall be taken to prevent as far as possible any influx of water, either from the adjacent soil or by means of pipes; and in the case of any such street box exceeding 1 cubic yard in capacity, ample provision shall be made, by ventilation or otherwise, for the immediate escape of any gas which may by accident have obtained access to the box, and for the prevention of danger from sparking; |
