24、A vii Foreword The purpose of this Specification is to define the requirements for electric cables provided with a lead sheath to provide protection against solvent penetration and corrosive attack. This publication was first issued in January 1957 as OCMA Specification Number ELEC-4, and revisions

25、were published in 1959 and 1973. In 1983, the Engineering Equipment Users Association (EEUA) and the Oil Companies Materials Association (OCMA) were combined to form the Engineering Equipment and Materials Users Association (EEMUA). The relevant EEMUA Technical Committee, which is now responsible fo

26、r the EEMUA and OCMA publications within their range of expertise, set up a small Working Group to revise the OCMA Specification No ELEC-4, and this became EEMUA Publication 133. In 2010-11, another EEMUA Work Group reviewed and updated the publication, resulting in this Edition 2 (2011). This secon

27、d edition updates the Specification to be compatible with the latest British (BS), European (EN) and international (IEC) standards and to include in its scope all types of electrical cables including instrument and communications. PVC and Elastomeric based-cables without a lead sheath are widely use

28、d, and this Specification is extended to include protection of these cables against solvent penetration, by the provision of a lead sheath where they are required to be used in areas that may be contaminated by petroleum-based solvents. Experience has shown that bitumen compounds do not assist in th

29、e long term in the prevention of solvent migration within the cable and they therefore continue to be excluded in this revised Specification. This Publication addresses only the Specification and provision of a lead sheath for the cable. However, where cables are used in hazardous areas, users are r

30、eminded of the need to follow the guidance given in IEC 60079 Part 14. In this IEC Standard, attention is drawn to the need to ensure that the cable under the lead must be substantially compact and circular; and gives details of how the termination of cables should be achieved.

Specification For Underground Armoured Cable Protected Against Solvent Penetration and Corrosive Attack 2.1 Scope This Specification supplements the relevant British, European and International Electrotechnical Commission Standards to provide a lead sheath where that Standard do

43、es not include a lead sheath. All cables and/or their components shall be in accordance with British, European or International Electrotechnical Commission Standards wherever they may be applied. 2.2 Bedding for Lead Sheath The lead sheath shall be applied over the insulated core of a single core ca

44、ble, or over the assembled laid-up cores, including any tapes or sheath used at the manufacturers discretion to hold the cores together or to protect the insulation during the sheathing process. 2.3 Lead Sheath For armoured and unarmoured cable, the cable sheath shall be lead alloy type PK021S as de

45、fined in Table 1 of BS EN 50307. The sheath shall be impervious to moisture, close fitting and free from defects. The diameter under the lead sheath shall be calculated from the tabulated overall diameter specified in the corresponding British Standard by subtracting twice the tabulated thickness of

46、 the outer layer(s) from the tabulated overall diameter. The lead thickness shall be obtained from Table 1 below. 2.4 Bedding for Armour The bedding for the armour shall be extruded. 2.5 Armour Single core cables shall be either non-magnetic wire armoured or unarmoured. For multicore cables, the arm

47、our shall consist of a single layer of galvanised steel wires. 2.6 Oversheath The oversheath shall be an extruded layer of black PVC unless otherwise specified at the time of the order. 2.7 Thickness and Other Requirements for Extruded Bedding, Armour and Extruded Oversheath The incorporation of the

48、 lead sheath shall not change the material thickness/wire diameter in the subsequent layer(s) as specified in the corresponding British Standard. EEMUA Publication 133 Specification for underground armoured cable EEMUA 4 The construction, materials and tests required for these layer(s) shall be thos

49、e specified in the corresponding British Standard, as referenced in this document. 2.8 Information Required with the Quotation The quotation shall include the approximate diameter over the lead and the approximate overall diameter of the cable for the purpose of cable gland selection. 2.9 British Standards Section 1.1.1 listed a number of relevant Standards including: BS 5467 Electric cables Thermosetting insulated, armoured cables for voltages of 600/100
