OPGW Design Variants | Standard Optical Ground Wire Configurations for Power Grid Protection

Typical Designs of OPPC

The Aluminium tube is surrounded by single or double layers of aluminium clad steel wires(ACS) or mix ACS wires and aluminium alloy wires.

Characteristic and Application

• Replacing one or several wires of the traditional conductor with stainless steel tube and strand the tube with AS/steel wires and AL/AA wires.
• Replacing one of the three phase conductors with OPPC, thus to form a transmission line which consists of one OPPC and two phase conductors.
• Mechanical and electrical performance can match the adjacent two phase conductors.
• OPPC can meet durative high temperature resistant which veri_x001f_ed by Temperature Cycling test and Short Current test.
• OPPC is applied to middle & high voltage power lines without ground wires such as 10kV, 35kV, 66kV and so on.
• Telecommunications for middle & high voltage power lines in urban and rural areas; Providing optical cables for building distribution automation station.

It looks like you're sharing data related to different types of OPPC cables under various temperature conditions. Based on the format, I see that each entry has multiple columns, which could represent:

• Cable Type (OPPC-XX/YY): Various OPPC (Optical Phase Conductor) models.
• Current Rating (measured in Amps, likely the maximum current each cable can carry under different temperature ranges).
• Temperature Ranges: Different operating temperatures: 40-70°C, 40-80°C, and 40-90°C.
• Other Values: The remaining values are likely related to different specifications, such as power loss, tensile strength, or specific electrical characteristics at those temperatures.
