Does anyone know the horizontal and vertical distance between Class A pipelines and 20KV high-voltage lines?

Does anyone know the horizontal and vertical distance between Class A pipelines and 20KV high-voltage lines? I’ve looked up the specifications in GB_50061-97 for overhead power lines of 66 KV and below regarding vertical distances. What does it mean by the horizontal distance being the height of the tallest pole/tower? In our case, the height of the utility poles is 18 meters, with 15 meters above the ground – does that mean the horizontal distance is 15 meters? If there are friends who understand, please share.
Those who are knowledgeable, please take a look at the attachment and discuss the horizontal and vertical distances between 20KV high-voltage lines and solvent pipelines.
Based on my understanding, for this marine colleague, the horizontal distance should correspond to the height of the tallest tower; if the tower is 30 meters tall, then the horizontal and vertical distance between Class A pipelines and the overhead tower should also be 30 meters； It is mainly to ensure a certain safety distance from special pipelines in the event that the tower collapses. If so, for Class A and Class B storage tanks, the horizontal safety distance between them must be 1.5 times the height of the tower to meet the design requirements ； And for a single LPG tank with a volume of over 200 cubic meters, the safety distance should be at least 40 meters! Additionally, the standards you referred to are no longer in use; please refer to the \"GB 50061-2010 Design Code for Overhead Power Lines of 66 kV and Below\"! The latest design specifications are attached for your reference! I hope this can help you!
This standard does not include the 20KV category. If you had to choose, should it be geared more towards 35KV or 10KV? Users would prefer it to be geared towards 10KV
Ahah, dear sea friend, no matter what the field of design is, the principle of aiming for excellence rather than settling for less must be followed – it’s a basic requirement in design! The specification refers to the design standards for overhead power lines below 66 KV; it already covers the design aspects of 20 KV overhead lines. Additionally, special requirements are specified in the standards for 66 KV and 35 KV lines. Please refer carefully to the detailed contents. In addition, it is necessary to first refer in detail to and comply with the relevant requirements of the \"GB50016-2014 Code for Fire Protection Design of Buildings\".
You’re right; it’s better to go high rather than low. It’s just that the standards required are high, which means greater investment is needed; is it possible to find a way around this?
Dear sea friend, you can also refer to the electrical design code \"DL 5449-2012 Technical Regulations for 20kV Distribution Design\" when making your designs; relevant instructions are available in that code as well! I’m attaching two pictures for your reference, but you still need to follow the national standards!
