Quintas & Quintas and Solidal
Quintas & Quintas Condutores Eléctricos SA. and Solidal Condutores Eléctricos, SA, leaders in the industry
of the aluminium power conductors have as principal activity the production of bare and insulated electric
conductors, their commercialization and the technical support with the assembly of the provided products.
Quintas Condutores in the sector of bare electric conductors and Solidal in the insulated cables, their
productions are mainly directed on aluminium products. This market segment, appeared, these last years,
strongly challenging, which is mainly due to the increasing aggressiveness from the manufacturing
companies. However, Quintas Condutores in the market of bare cables and Solidal in insulated cables are
leaders of the sector.
The two companies followed a strategy based on two orientations: to carry out a progressive vertical
integration, increasing, thus, the level of the added value of the products that they sell and to remain
updated from the technological point of view, while they invest regularly in advanced technology equipment
and productivity and simultaneously in Technical Boards of recognized rename and their adequate formation.
Nowadays Quintas & Quintas and Solidal have all the equipment and “know-how” necessary to the industrial
process, to produce and transform the conductors indicated hereafter:

All Aluminium Alloy Conductors for overhead lines
Construction:
This bare concentric-lay stranded conductor is constructed with a straight round central wire surrounded by one
or more layers of helically wires.
Applications:
Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high strength
aluminum alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy
gives AAAC higher resistance to corrosion than ACSR.

Aluminum Conductors Steel Reinforced for overhead lines
Construction:
ACSR is a concentrically stranded conductor composed of one or more layers of aluminum wire stranded with a
high strength coated steel core. The core may be single wire or stranded depending on the size.
The proportions of aluminum and steel can be varied to obtain the relation between current-carrying capacity
and mechanical strength best suited to each application.
Additional corrosion protection is available through the application of grease to the core or infusion of the
complete cable with grease.
Applications:
Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal
strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing
ampacity.

Aluminium Low Voltage Aerial Bundled Conductors
Construction:
Round stranded and compacted aluminium conductors (phases/neutral).
Aluminium alloy messengers (neutral conductor) in several cross sections, namelly 54,6, 70, 80
and 95 mm2 can also be included in the bundle.
XLPE Insulation, UV resistant
Voltage
0,6/1 kV
Applications:
The aluminium aerial bundled conductors are mainly used for the low voltage distribution
networks, namely in the rural or suburban areas, due to several specific advantages, like:
- good network performance (low failure rate)
- possibility to perform repairs and interventions in the lines under tension
- reduced installation cost
- reduced forest fire risk
- particulary suitable for heavily polluted environments
- good resistance to acid rain salt spray
Standards:

Aluminium or Copper Low Voltage Cables
Construction:
Aluminium conductors (solid/stranded, round/sector shaped)
XLPE insulation.
Polyester assembling tape
PVC bedding (armoured cables)
Double helix tape (multi core armoured cables) or aluminium tape (single core cables)
PVC outer sheath (LDPE sheath supplied on request)
Applications:
Power plants, underground distribution networks, industrial plants.
The solid conductor cables are particulary suitable for the low voltage circuits, between the
transformers and main distribution boards.
The cables can be installed in ducts or open air (the armoured versions are generally used in
undergruond circuits, directly buried in the soil).

Aluminium Medium Voltage Aerial Bundled Cables
Construction:
Round stranded and compacted aluminium or copper conductor.
Inner semi-conducting layer.
XLPE insulation.
Outer semi-conducting layer (strippable or full bonded ).
Metallic screen (copper tape).
Non-metallic outer sheath (PE or PVC).
Voltage
6/10 (12) kV
8,7/15 (17,5) kV
12/20 (24) kV
18/30 (36) kV
Applications:
The medium voltage bundled cables are particularly suitable for overhead transport and
distribution networks in places were an underground network would be unrealisable (rocky soil,
forest and mountain areas).
This cables are also frequently used in temporary connections, as they can be easily installed and
removed. The overhead bundled cables are also an ideal solition for heavily polluted ar maritime
environments, and they resist rather well to frost and low temperatures.
