Self-supporting protected insulated single-core high-voltage wire with a light-stabilized XLPE insulation
20 kV; 30 kV

Self-supporting protected insulated single-core high-voltage wire with a light-stabilized XLPE insulation

TU U 27.3-31850229-023:2007
IEC 4743:2007

 

Application

SIP-3, SIP-3…g, SIPn-3, SIPn-3…g (-3, -3…, -3, -3…)

20 kV; 30 kV

These wires are used for laying aerial electric power lines for the rated voltage from 10 kV till 35 kV at a rated frequency of 50 Hz.

These wires are intended for overhead electric power lines in moderate, cold and tropical climate.

Climate class (NF), location categories 1, 2 and 3.

Wire SIP-3…g: self-supporting protected insulated single-core high-voltage wire with sealed conductor, light-stabilized XLPE insulation.

Wire SIPn-3: self-supporting protected insulated single-core high-voltage wire with light-stabilized XLPE insulation. This wire have flame-retarding ability when laid in bundles.

Wire SIPn-3…g: self-supporting protected insulated single-core high-voltage wire with sealed conductor, light-stabilized and flame-retardant XLPE insulation. These wires have flame-retarding ability when laid in bundles.

Ordering designation of cable: SIP-3 1×95–35.

Conformity the foreign-made analogues:
SAX, PAS (SFS 5790, SFS5791; Finland),
AALXS, AALXSn, AFLwsXS, AFLwsXSn, AAsXS, AAsXSn, AAsXSnu (Poland).

 

Construction

Conductor
Multicore aluminum-alloy stranded compacted round conductor.
Wires with sealed conductor are designated as SIP-3 1x95g.
Wires with sealed conductor are contain a water-blocking material or materials.

Insulation
Laid-on by extrusion from cross-linked polyethylene (XLPE).

Technical characteristics

Performing only single-core wires

Breaking strength of conductors of self-supporting protected wire is described next table:

Nominal conductor cross-section, mm Breaking strength of conductor, kN, not less
25 7.4
35 10.3
50 14.2
70 20.6
95 27.9
120 35.2
150 43.4
185 53.5

Permissible current loads calculated for the ambient temperature +25C, wind speed 6 m/s and solar radiation intensity 1000 Vt/m, and permissible short-circuit currents for these wires are described in cross-section «Reference data».

Wires are bending – resistant during installation. Suspension of wires in overhead power lines must meet the requirements of Electrical Installation Regulations.

Manufactured wire lengths may be agreed with the customer request. Transportation and storage of wire must accordance with GOST 18690.

The manufacturer can ensure compliance of wire quality with requirements of DSTU 4743 and current technical specification, provided all terms of transportation, storage, installation and use have been observed.

On customers request other marking of wire is allowed.

Wires are delivered on drums.

All products are certified.
