Third, check the quality of the aluminium foil: coaxial Phase Stable Cable plays an important role in shielding the aluminium foil, which plays an important role in avoiding external open-circuit signal interference and preventing cable TV signal leakage, so the quality of the aluminium foil should be checked for new coaxial Phase Stable Cable. Firstly, cut open the sheath layer and observe whether the surface of the woven wire and aluminium foil layer maintains a good lustre; secondly, take a section of Phase Stable Cable, wrap it tightly around a small metal shaft, straighten it and turn it around in the opposite direction, repeatedly get it several times, then cut open the sheath layer of Phase Stable Cable to see whether the aluminium foil has any fracture, or you can cut out a small section of aluminium foil and rub it in your hands repeatedly and stretching, after repeatedly rubbing and stretching still not broken, with a certain toughness for the cooperation of the vomit, otherwise for inferior products.

Fourth, check the coaxial Phase Matched Cable's woven wire: coaxial Phase Matched Cable's woven wire plays an important role in the shielding of coaxial Phase Matched Cable, and whether it is in the centralized power supply cable TV lines or power supply return lines, coaxial Phase Stable Cable quality inspection must be A careful observation of the tightness and flatness of the textile mesh is carried out by cutting open the outer sheath of the coaxial Phase Matched Cable, cutting a small section of the coaxial Phase Matched Cable woven mesh, identifying the quantity of the woven mesh, if it matches the value of the index given as qualified, and additionally measuring the single textile mesh with a spiral micrometer, in comparison with the same price, the The thicker the quality of the wire diameter, the better.

Fifth, test the tightness of the outer sheath extrusion: high quality coaxial Phase Matched Cable outer sheath are wrapped very tightly, so as to reduce the gap within the shield layer, to avoid air entering the oxidation, to prevent the relative sliding of the shield layer caused by the electrical properties of the drift, but too tightly packed will cause inconvenience stripping the head, increasing the difficulty of construction. The inspection method is to take a 1m length of Phase Matched Cable and peel off the shield at the end, so that the core cannot be pulled out by force.

Sixth, observe the shape of Phase Stable Cable into a circle: Phase Matched Cable into a circle is not only reflected in the appearance of beauty, more importantly, or Phase Stable Cable quality issues. The Phase Matched Cable and the Phase Matched Cable into a circular parallel contact between the whole, can reduce the mutual force between the Phase Matched Cable, stacking is not easy to deformation damage, so in the acceptance of the quality of Phase Matched Cable can not be careless and careless to look at the two eyes, to carefully and carefully You have to observe carefully.
