1. Siaizfi

Thia section specifies requirements for end dimensions of single and mufti-core cables having reduced fire propagation performance. These cables are insulated with either cross-linked polyethylene, <XLPE), or vulcanised EPR rubber compound. extruded directly on the conductor in halogen free fire retardant cables.

The maximum continuous conductor temperature shall not exceed 70°C. The maximum temperature for abort -circuit condition for not more than Sa is 160²⁹³⁰Сь

This section covers from V to 4-cors halogen free fire retardant cables having aluminium or copper conductor.

2. Additional general requirements

The folowing general requirements shall be read in conjunction with those given in Part 1

2 J Identification of cores

Cable core identification shall be made by using colours, or for phase cores with numbers on black cores,

5. Rated voltage

6. Standard

fri element 3 the conductor metal shak be indicated, If there are conductors of differing metals in the cable.

Element 4 Is used to indicate the presence or absence of a protective conductor. The tetter N indicates no protective conductor in the cable and the better S indicates a protective conductor in the cable. No tetter is used H the cable can be used a* either ■n N or an S type.

The external marking shall be embossed or indented on the oversheath.

The group of external marking elements shall be repeated after not more than Im.

A means of identifying the year of manufacture of the cable shall be provided throughout the length of the cable.

If the identification « made by marking on the surface, it shall comply with the requirement a given in sub-clause 2.3.1 in respect with the maximum distance for repeating the marking,

If the mark of an Approval Organisation is used it shall be provided throughout the length of the cable and it shall comply with the marking requirements of Subcteute 2,3.1.

The use of optional marking і» permitted. Where such marking is made it shaH be throughout the length of the cable.

2.4 Additional tsst reauiremants

The test is carried out as a dry test for the complete cables. The test voltapa is connected between the ewer conductor to be rested, end the other conductors including the concentric conductor connected together. АП the tenner conductors shal be tested.hot 54-4

HD 604 51:1994

Part 6 Section I

The teat voltage shall be either 4kV &OHz AC or 16 kV DC- The testing time h five minutes for AC end one minute for DC- The voltage is increased gradually to the specified value.

For throe phase cables the test may be carried out as a three phase test when the voltage between phase* Is V3 times the single phase test value given above.

The test method is given in HD 605 sub-clause 3*3.1, and the requirement at the test temperature of + 90^eC is 10** Dm,

2.4,3,1 Range of approval for single core cables

Type approval for the complete range of cables for single core type Is obtained by carrying out the tests given in Table 1, on minimum of one cable size.

2 4,3.2 Ranos of approval for mJtt-core cables

Type approval for the complete range of cables specified for miJti-cora typo ts obtained by carrying out the tests given in Table 1. on minimum of on* cable size.
