with the continuous expansion of the market, the economic system reform, and now more industries are taken to export the way.
then the cable is the same, for cable exports need to know:
technical standards
foreign cable generally require the use of iec or the british standard, american standard advanced standard, therefore only the familiar domestic standard is not enough, but also familiar with international standards.
two, laying conditions
in western asia, southeast asia and other regions of the environmental conditions are relatively special, such as some regions of the extreme maximum temperature of 50 degrees, the highest daily average temperature of 40 degrees c
therefore, it should be noted that the technical parameters related to the environment (such as the correction coefficient of the carrying capacity) should be taken into account in the technical data.
three, cable structure
due to the cable laying environment, the cable structure in addition to meet the standard requirements, there are still some additional requirements for this,
enterprises should pay attention to the design and manufacture of cable. for example, if an enterprise is exporting to the middle east, it is in the process of technical communication,
the structure and dimensions of the cable have been confirmed by the other party. in order to meet the requirements of the shielding interface of the cable, they are calculated according to iec 949 (1988) standard,
the width, thickness and number calculation of cable shielding strip, the double wrapped copper strip, to meet the requirements of waterproof cable, cable shielding strip wrapped in inside and outside the water resistance of semi conductive tape,
the waterproof material is used to fill the bag and the inner sheath is made of polyethylene material. the outer protective layer adopts termite resistant material,
and coated with graphite layer in accordance with iec229 on the cable sheath pressure test. cable marking to meet the requirements of the standard and the user's special requirements.
four, cable packaging
the export of cable, the delivery disk is used with the market or steel plate structure, and fully enclosed with iron or wood packaging.
the size of the cable tray should be considered in addition to the length of the cable and the minimum allowable bending radius of the cable.
marks should be strictly in accordance with the request. due to the fact that the packaging of export cable is more complicated than that of domestic cable, the cost and delivery time will be affected,
to this end, we must pay attention to the contract.
five, other matters needing attention
before delivery, to provide users with the main technical parameters of the cable, cross section, such as the laying of specifications, test reports must be shipped with the goods.
the technical data shall be kept intact; the length of the cable shall be strictly controlled, and the delivery length error shall be minimized.
all export products must be inspected by the state commodity inspection authorities, and issued a commodity inspection certificate.
china has joined the wto, as china's national enterprises, the market competition should not be confined to the domestic market.
in fact, the quality of china's cable continues to improve, the cost continues to decline, as long as the attention to pre - and post sales work.
