Define the role of the substation in the network<\/h2>\n<p style=\"margin: 0 0 16px; line-height: 1.7;\">An electrical substation is the point where equipment changes voltage, switches circuits, protects feeders, or connects sections of a power network. The exact role may be generation step-up, transmission, distribution, industrial intake, or a local packaged solution. Its purpose is defined by the one-line diagram, not by the size of the enclosure.<\/p>\n<p style=\"margin: 0 0 16px; line-height: 1.7;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1635 aligncenter\" src=\"https:\/\/shenhengglobal.com\/wp-content\/uploads\/2026\/06\/1.-0.4KV-Low-Voltage-Switchgear-LT-Panel-3.webp\" alt=\"Define the role of the substation in the network\" width=\"750\" height=\"750\" srcset=\"https:\/\/shenhengglobal.com\/wp-content\/uploads\/2026\/06\/1.-0.4KV-Low-Voltage-Switchgear-LT-Panel-3.webp 750w, https:\/\/shenhengglobal.com\/wp-content\/uploads\/2026\/06\/1.-0.4KV-Low-Voltage-Switchgear-LT-Panel-3-300x300.webp 300w, https:\/\/shenhengglobal.com\/wp-content\/uploads\/2026\/06\/1.-0.4KV-Low-Voltage-Switchgear-LT-Panel-3-150x150.webp 150w, https:\/\/shenhengglobal.com\/wp-content\/uploads\/2026\/06\/1.-0.4KV-Low-Voltage-Switchgear-LT-Panel-3-500x500.webp 500w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><\/p>\n<h2 id=\"Part-2.-Separate-a-substation-from-a-power-station\" style=\"margin: 42px 0 14px;\">Part 2. Separate a substation from a power station<\/h2>\n<p style=\"margin: 0 0 16px; line-height: 1.7;\">A power station produces electricity. A substation generally receives, transforms, switches, measures, or distributes electricity that has already been generated. Projects sometimes combine these facilities on one site, but the engineering functions and equipment schedules are different.<\/p>\n<h2 id=\"Part-3.-Recognize-the-equipment-that-must-work-together\" style=\"margin: 42px 0 14px;\">Part 3. Recognize the equipment that must work together<\/h2>\n<p style=\"margin: 0 0 16px; line-height: 1.7;\">A distribution substation may include medium-voltage switchgear, a transformer, low-voltage distribution equipment, protection and metering, earthing, cables, and an enclosure. The package must be coordinated so voltage class, fault duty, protection settings, clearances, and cable interfaces agree with the approved design.<\/p>\n<p style=\"margin: 0 0 16px; line-height: 1.7;\"><img decoding=\"async\" style=\"max-width: 640px; width: 100%; height: auto; display: block; margin: 0 auto; border-radius: 8px;\" src=\"https:\/\/shenhengglobal.com\/wp-content\/uploads\/2026\/06\/1768790926512044.webp\" alt=\"Project planning for electrical substation\" \/><\/p>\n<h2 id=\"Part-4.-Choose-the-layout-from-site-constraints\" style=\"margin: 42px 0 14px;\">Part 4. Choose the layout from site constraints<\/h2>\n<p style=\"margin: 0 0 16px; line-height: 1.7;\">A conventional substation can distribute equipment across a dedicated building or yard. A compact or prefabricated arrangement integrates major equipment in a factory-assembled enclosure, which can simplify site work when the layout and interfaces are fixed early. Foundation, lifting route, cable entry, ventilation, and maintenance space still require site coordination.<\/p>\n<h2 id=\"Part-5.-Ask-the-project-questions-before-selecting-a-package\" style=\"margin: 42px 0 14px;\">Part 5. Ask the project questions before selecting a package<\/h2>\n<p style=\"margin: 0 0 16px; line-height: 1.7;\">Confirm the incoming and outgoing voltages, transformer rating, MV and LV feeder arrangement, short-circuit level, environmental conditions, utility metering requirements, and local approval process. These inputs determine whether a compact solution is suitable and what it must contain.<\/p>\n<h2 id=\"Part-6.-Use-a-compact-package-as-a-starting-point-,-not-a-substitute-for-design\" style=\"margin: 42px 0 14px;\">Part 6.
