VISIBLE RESULTS WITH INVISIBLE WIRING

In the 1960's, when Lima began to expand, electric wiring used to be installed underground. Now, 30 years later, our urban landscape projects an image of great disorder due to the presence of aerial wiring.

The latter not only damages the urban landscape but also creates a series of risks that must be timely assessed so as to guarantee a safe and comfortable future for our cities.

• Technical Considerations for Selecting COPPER.
• Safety and accident prevention.
• Efficiency and Economy.

TECHNICAL CONSIDERATIONS FOR SELECTING COPPER

Copper is the metal with the best electric and mechanic properties for underground wiring: high electric conductivity, excellent mechanical behavior, hard to match corrosion resistance and high secondary recovery that produce minimal negative effects on the environment.

COPPER is Peru's main export product and it generates the greatest amount of foreign revenue for the country. Today we rank sixth in the world’s copper production and we keep making progress. We Peruvians must pay special attention to the future of copper.

Let’s Use The Copper That Our Country Produces

SAFETY AND ACCIDENT PREVENTION

• Peru’s marine littoral is 3,080 km. long. Its environmental aggressiveness causes fast metal deterioration, mainly through abrasion and corrosion. Underground Copper Wiring avoids problems and accidents that natural agents can cause.

• COPPER is a material technically superior to others. It is very convenient to use copper conductors in the productive sector, since its confidence and security indices must be higher than those in the other sectors.

• Underground Copper Wiring protects us from the possibility of a traffic accident, a kite tangled up in an aerial cable, badly installed fireworks or any other such risk. Let us be cautions and avoid waiting until a misfortune occurs.

Let's guarantee safety, let's use more copper

EFFICIENCY AND ECONOMY

When the technical and economical characteristics of COPPER are compared against those of aluminum, in low voltage aerial wiring, we can notice that:

• With the same gage, the energy transport capacity is 28% greater in a COPPER conductor than in an aluminum conductor.

• With the same current or energy transmitted along the same line length, an aluminum conductor shows greater loses (60%) than a COPPER conductor. (Joule Effect).

• With the same gage and amount of energy transmitted with the same voltage dip, a COPPER conductor permits a distance between 30% to 50% greater than that allowed by an aluminum conductor.

• To transport the same amount of energy, of equal quality, a 2-gage normalized aluminum conductor is required; bigger than that required for a COPPER conductor.

• Weather conditions in Peru’s coastal region cause corrosion problems in many electric lines with aluminum wiring, making their lifetime shorter than that of underground COPPER wires.

We all agree that efficiency must be taken into consideration as a design criterion in electric supply systems. COPPER is an efficient material for it reduces energy losses by increasing the conductors’ section, it also improves voltage and/or better reassigns the load in the system.

Save time and thus money, the solution is Underground Copper Wiring
