Many customers ignore the voltage level parameter when choosing ADSS optical cables, and ask why voltage level parameters are needed when inquiring about the price? Today, Hunan GL will reveal the answer to everyone:
In recent years, the requirements for the transmission distance have been greatly increased, and the corresponding voltage level has also increased a lot. Distribution lines above 110KV have become a common choice for design units. This puts forward the performance (anti-tracking) of ADSS optical cables. Due to higher requirements, AT sheath (tracking resistant sheath) has officially been widely used.
The use environment of ADSS optical cable is very harsh and complicated. First, it is laid on the same tower as high-voltage lines, and it runs near high-voltage transmission lines for a long time. There is a strong electric field around it, which makes the outer sheath of ADSS optical cable extremely easy to be damaged by galvanic corrosion. Therefore, under normal circumstances, when customers understand the price of ADSS optical cable, we will ask clearly the voltage level of the line in order to recommend the most suitable ADSS optical cable specification.
Last Thursday, we received a call from a customer. In July, we received a inquiry from them, The specification is ADSS-24B1-300-PE, but the line voltage level is 220KV. Our suggestion is to use ADSS-24B1-300-AT. including the designer also recommends the use of AT sheathed (tracking resistant) optical cables, 23.5KM lines, plus supporting fittings. Due to budget issues, they were eventually purchased the cable from a small manufacturers and kept the price low. but Now they told us the circuit has been broken down in several places. From the photo, it is obvious that it is caused by electric corrosion. This is also cheap for a while, which affects the normal use in the later stage. Finally, we gave the solution to re-start at the breakpoint. Connect, with several connector boxes, of course this is only a temporary solution (if there are many breakpoints, it is recommended to replace the line).
Of course, the performance requirements of the AT sheath (electric tracking resistance) also make its price slightly higher than the PE sheath (polyethylene), which also leads some customers to consider the cost and think that it can be erected normally. Consider more the impact of voltage level.
So far, Hunan GL’ ADSS products and supporting hardware have been exported to more than 170 countries around the world, especially in the South American region. The ADSS, ASU and supporting hardware products produced by us are very popular with Guanglian. After the project is formed, it has been well received.
Hunan GL has been in the wire and cable industry for 17 years and has formed a good brand effect at home and abroad. Therefore, we are dealing with customer inquiries, from quotation to production, to inspection, delivery, to construction and acceptance. In every aspect, we strive to think about the problem from the perspective of the customer. What we sell is the brand, the guarantee, and the reason for long-term development.
