Description of the measure

This Tanzania Standard specifies requirements for PVC-covered conductors for overhead power lines. These requirements are limited to the PVC covering and to the testing thereof after application to the conductor.

1.2 Two minimum thicknesses of covering have been standardized as follows;
Designation Minimum thickness of covering

Type 8 0.8 mm
Type 16 1.6 mm

1.2.1 Type 8 is intended for use only where the operating voltage of the power line does not exceed

650 V r.m.s. between any two conductors or 250 V r.m.s. between any conductor and earth.

Under these operating conditions, it is suitable for:
a) Crossings of telecommunication lines to guard against contact.
b) Proximities to telecommunication lines to guard against contact.
c) Lines (particularly service lines) to be accessible from buildings.

1.2.2 Type 16 is intended for use only where the operating voltage of the power line exceeds 650 V r.m.s. between any two conductors or 250 V r.m.s. between any conductor and earth, but does not normally exceed 11 kV.r.m.s between conductors or 6.6 kV.r.m.s between any conductor and earth. The earthing of a neutral point of the system through an arc-suppression coil is not precluded. If arrangements exist for clearing earth faults without undue delay under these operating conditions, type 16 is suitable for crossings of telecommunication lines and proximities to them.

1.3 These covered conductors shall not be used for purpose other than over-head fines.
