Plastic insulated control cables –
Part 1. General requirements
1 Scope
This Part of GB/T 9330 specifies the codes, marking, technical requirements and inspection
rules of the extruded insulated and sheathed control cables with the rated voltage U0/U ≤
450/750V.
This Part is applicable to the control cables, with the rated AC voltage U0/U ≤ 450/750V, that
are used in the control and monitoring loops and protective lines.

3 Terms and Definitions
The following terms and definitions AND those defined in GB/T 2900.10-2001 are applicable
to this Part.
3.1
8 Delivery Length
The cable shall be delivered according to the length agreed by both parties. The length
measurement error shall not exceed ±0.5%.
9 Inspection Rules
9.1 The cables shall not be shipped out of the factory until they pass the inspection of the
manufacturer' quality control department. The delivered products shall be accompanied by the
quality inspection certificate.
9.2 The products shall be checked for acceptance according to the specified test items.
9.3 The sampling quantity of the delivered lot shall be decided by both parties. It shall be
carried out according to the manufacturers' requirements if the user does not require.
If the results of sampling items are unqualified, double quantity of samples shall be taken for
the re-test on the unqualified items. If the results are still unqualified, 100% inspection shall
be carried out.
9.4 When there is dispute over the acceptance between the manufacturer and the user, the
arbitration test shall be carried out by the authority accepted by both parties.
10 Packing
10.1 The coiled or reeled cables shall be winded regularly and packed in good order. The

The cable sockets shall be sealed reliably. The cable sockets extruded out of the reel shall be
set with protective cover.
10.2 Each coil or reel shall be attached with the label to indicate.
a) Manufacturer's name;
b) Model and specification (unit. mm2);
c) Rated voltage (unit. V);
d) Length (unit. m);
e) Mass (unit. kg);
f) Manufacturing date (year, month);
g) Standard serial number or certification mark;
h) Correct rotation direction of cable coil.
10.3 When casing, the case shell shall be indicated with.
a) Manufacturer's name;
b) Model and specification (unit. mm2);
c) Rated voltage (unit. V);
d) Standard serial number or certification mark;
e) Physical dimension and mass (unit. kg) of the case;
f) Marks of "keep away from moisture" and "no throwing".
For the shield of double-layer metal tapes, Δu equals to two times of the thickness of metal
tape (see 6.4.1 and 6.4.2).
For the braided shield with copper wires, Δu equals to 2.5 times of the diameter of the single
braided wire (See Table 3).
A.2.5 Fictitious diameters of inner liner (if existed)
For the armoured cables, the fictitious diameter Db of the inner liner shall be calculated by -
the corresponding value of diameter that is calculated in A.2.3 or A.2.4 PLUSES 2 times of
the specified nominal thickness of inner liner, as the following formula.
Db=Dt+2Δb or Db=Du+2Δb
Where.
Δb - the nominal thickness of inner liner (See Table 4).
