Precautions when purchasing HYA cable

It can transmit audio signals and also accommodate digital broadband such as ADSL for outdoor laying. HYA adopts aluminum-plastic bonded sheath for better waterproof performance, and the whole cable can be inflated and maintained, but its sheath is aluminum-plastic bonded sheath, so it is more suitable for outdoor overhead. HYA is mostly used outdoors. That is to say, the line between the building and the telecommunications bureau uses HYA. You can look at the telecommunications line on the road. Absolutely HYA. HYV adopts PVC sheath, which means PVC has better softness and better electrical properties than HYA, but its waterproof performance is far less than HYA, which is suitable for indoor laying. Most of the voice trunks used in the building can of course be replaced by three major logarithms. Both HYA53 and HYV22 belong to the armored cable type 53 which is a single-layer longitudinal steel strip armor and the 22 type is a double-layer steel belt wrapped armor. When buying HYA, first look at the wire packaging card of the roll to see if there is a quality system certificate; see if the certificate is standardized; see if there is a factory name, site, inspection chapter, production date; see if the trademark is printed on the wire, Specifications, voltage, etc. Also look at the cross section of the copper core of the wire, the superior color of the copper color is bright, the color is soft, the copper core yellow is reddish, indicating that the copper used is of good quality, while the yellow and white is the reflection of low quality copper. It is advisable to repeatedly bend a wire head by hand. Anyone who has soft hand feeling, good fatigue resistance, strong plastic or rubber feel and no crack on the wire insulation is a superior product. The outer plastic skin of the wire should be bright and fine, and should be ignited by a lighter. Take a section of insulation and see if its core is in the middle of the insulation. If the power is not high, the eccentricity caused by the process is not high. If the power is small, it can be safe. If the power consumption is large, the thinner side is likely to be broken by the current. Be sure to look at its length and core thickness. In the relevant standards, the wire length error should not exceed 5%, and the cross-sectional diameter should not exceed 0.02%. However, there are a large number of short lengths in the market, and the cross-section is falsified (for example, the cross-section is 2.5 square millimeters). The line is actually only 2 square millimeters thick.
