4.3 Construction of cables
4.3.1 General
The permissible operating temperature of conductors shall not be lower than the maximum operating
temperature of the cable as a whole.
4.3.2 Cabled cores
The lay length of the outer lay shall not be less than eight times and not more than 16 times the nominal
diameter of the cabled cores.
The core shall not be spliced.
Where filler cores are used, this shall be specified in the product standard.
4.3.3 Screened cables
4.3.3.1 General
The individual strands used for the screen shall be free from kinks, loops or breaks; their surface shall
be free from corrosion and other contamination. They shall satisfy the mechanical tests in EN 3475-505
to EN 3475-508 before use.
The screen shall be in contact with all the cabled cores.
Where spiral screening is used, the lay direction shall be contrary to that of the cabled cores.
4.3.3.2 Joints
Joints in the individual strands of the screen shall be made by soldering or by laying the individual
strands together over a length of at least 10 mm.
There shall be no more than one joint per 3 m cable length (measured between different individual
strands).
4.3.3.3 Braid screen pushback capability
In accordance with Table 1, test 6.48.
4.3.3.4 Angle of spiral screening or braiding
The angle γ of spiral screening or braiding (as shown in Figure 1), measured against the longitudinal
axis of the cable shall be at least 10°.
4.3.3.5 Screen coverage
The screen shall have a coverage β of at least 90 % for spiral screening and at least 85 % for braiding.

Figure 1 — Screen coverage
The cable covering is calculated using the following formula:
— for spirals:
U = π (D + d) and S = π (D + d) tan α F = U’ Z/U = n d Z/[π (D + d) sin α] β = F × 100 (%)
— for braids:
U = π (D + 2 d) and S = π (D + 2 d) tan α
— for spiral screen:
the maximum length T of the non-covered area is 2 mm, and
the relative aperture (versus lay length) of the screening 100 T/L shall be less than 5 % (see
Figure 2).
