Pole Height is 13 Meter: On an undivided street, generally Meter, 2.5 Meter or 4 Meter arms are used. Pole Height is 13 Meter: divided Street, typically have a 8 Meter wide center median to divide opposing lanes of traffic. On streets where the light poles are installed in a raised median, two 4 Meter arms oriented 180° apart are used.

Section 6: Spacing of Light Poles

Standard Spacing for Freeways and Complete Interchange Lighting

For freeway lighting, TxDOT has standard spacings for conventional light poles to provide the minimum AASHTO-recommended illuminance levels. If higher light levels are needed, the spacing should be calculated with lighting design software.

50 ft. poles with 400W EQ LED luminaires may be spaced 270 ft. apart to provide the minimum recommended freeway illuminance levels. This will extend up to 60 ft. across the roadway from the luminaire. If wider roadways need to be lit, the spacing should be calculated with lighting design software.

40 ft. poles with 250W EQ LED luminaires may be spaced 220 ft. apart to provide the minimum recommended freeway illuminance levels. This will extend up to 50 ft. across the roadway from the luminaire. If wider roadways need to be lit, the spacing should be calculated with lighting design software.

Standard Spacing for Roadways Other than Freeways

To determine the required illumination levels for roadways other than freeways, use the tables in Section 2 of this chapter, the AASHTO Roadway Lighting Design Guide, or ANSI/IES RP-8-14, Roadway Lighting. An illumination program capable of calculating luminance or illuminance levels is required to determine if adequate illumination levels have been achieved. White keyboard for mac.

Merge and Diverge Lanes

For partial interchange lighting, the first light pole for merge and diverge lanes should begin at the end of the weave area and continue to within 50 feet of the painted gore, as shown in Figure 6-2.

Lighting Near Overpasses

Poles supporting lighting for roadways beneath overpasses should be placed at least 20 feet from the overpass to reduce glare on the overpass.

Determining Mounting Height

Mounting height depends on the number of lanes to be lighted. The designer must use the mounting height that allows for adequate illumination levels. If proper lighting cannot be achieved with one pole, the designer should consider using additional poles to provide proper coverage.

Electric street lighting has been standardized since very recently (the 1987 NFC 17-200 French standard). “Quality” and sustainability safeguards for construction are regulated. All people involved operating on a street lighting installation – installers, inspection bodies or building owners – must be particularly vigilant about the risk of indirect contact (Electrostatic). Besides standard compliance, the customer requires a cost-controlled installation. Therefore it is imperative to avoid cable and protection oversizing. To meet efficiently these requirements through a successfully completed working method, companies are now integrating normative and powerful software for designing secure facilities.

elec calc™ EP is an electrical grid calculation software for outdoor lighting installations in accordance with current standards (French NF C17-200 and UTE C17-205 guide). Redshift for cinema 4d mac.

elec calc™ EP is a complete and easy to use professional tool, which meets the needs of engineering offices, local administrations’ technical departments, local organizations for electrical network supervision and maintenance and installation inspection organizations.

elec calc™ ep is designed for electricians to size their outdoor lighting installations. elec calc™ EP allows the sizing of cables and protections while taking into account the voltage drops and the short-circuit currents according to the distribution of light fixtures. It also provides information on the compliance status through a clear and user-friendly interface.

elec calc™ EP can be used to:

• Design, optimize and control an outdoor lighting installation.
• Size the entire installation network based on electrical constraints:
  – Voltage drops,
  – Short-circuit currents,
  – Distribution of lights,
  – Type of light fixtures.
• Edit required documents, drawings and calculation notes to ensure the installation validation and compliance.

elec calc™ ep was developed with the technical collaboration of Inéo Réseaux Ouest, a GDF-Suez Group company involved in the development and distribution of electricity.

• As a new-generation software, elec calc™ ep works in real-time with instant responses.
