/* บริษัท เจพีเอส พาวเวอร์ เทค จำกัด — สไตล์ชีตหลัก
   แนวคิด: ลูกถ้วยฉนวนพอร์ซเลนสีน้ำตาลตัดกับท้องฟ้า ยิ่งแรงดันสูง พวงลูกถ้วยยิ่งยาว
   จำนวนลูกถ้วยจึงใช้บอกระดับแรงดัน แรงสูง แรงกลาง แรงต่ำ และเป็นเครื่องหมายใต้หัวข้อ
   สี: น้ำตาลเคลือบพอร์ซเลน ฟ้าท้องฟ้า ขาวเมฆ และเหลืองป้ายเตือนเป็นจุดเน้นเล็ก ๆ */
