Main Components of Overhead Electrical Standards (ES43 Series)

1. General Design Guidelines

• Clearances (to buildings, roads, railways, vegetation)

• Pole loading calculations

• Span lengths and tensions

2. Structures and Materials

• Pole specifications (wood, steel, composite)

• Crossarms, insulators, guy wires, and anchors

• Mounting brackets and hardware

3. Conductor Installation

• Types of conductors (bare and insulated)

• Phasing, spacing, and bundling

• Sag and tension requirements

4. Transformers and Equipment

• Pole-mounted transformers (single- and three-phase)

• Capacitor banks and reclosers

• Surge arresters and fuses

5. Service Connections

• Service drop configurations (residential/commercial)

• Metering equipment

• Triplex and duplex cable use

6. Grounding and Bonding

• Ground rod placement

• Ground resistance targets

• System grounding types (multi-grounded neutral)

7. Street Lighting and Joint Use

• Mounting of street lights on power poles

• Sharing poles with telecom providers

• Clearance requirements for joint-use facilities

8. Safety and Work Procedures

• Working clearances for live-line work

• Signage and hazard marking

• Emergency repair guidelines
