35kv concrete pole

Types of 35kv concrete poles

Wholesale buyers can find different types of 35kv concrete poles for various applications. Some common types include dual-purpose, spun-cast, and hybrid concrete steel pole combinations.

• Dual-Purpose Poles: Dual-purpose concrete poles support both power lines and telecommunication lines. They reduce the number of poles needed along pathways. This type of utility pole has cross-arms or braces to hold telecom wires at a safe distance above power lines. The design of dual-purpose poles prevents interference between different types of wires.
• Spun-Cast Concrete Poles: Spun-cast concrete poles are made by spinning concrete in a mold. This method creates lighter poles that are easier to handle compared to traditional concrete casting. These poles have similar weight and strength to regular concrete poles. Spun-cast concrete poles also have better resistance to harsh weather conditions and electrical conductivity. Their design provides more space between power lines and the pole. Spun-cast concrete poles can support more cables at the same height.
• Hybrid Concrete Steel Pole Combinations: Hybrid concrete-steel poles consist of a steel core and a concrete shell. This combination provides extra strength and durability. It also increases resistance to damage from floods or strong winds. The steel core gives more stability by preventing bending or breaking under pressure. The concrete outer layer adds toughness and withstands rough environments.

Specification and maintenance of 35kv concrete poles

Typical concrete electric poles specifications and their maintenance requirements are as follows.

• Specification

  - The core pole length is 12 feet, while the upper, middle and lower belly fenestrated sections are 4, 8, and 3 feet long. The core pole bottoms are domed for better soil contact.

• Maintenance

  - Apart from the usual inspection and maintenance activities of other cement electrical poles, caution must be taken not to damage the core belly in any way. For example, it should not be covered with more than two inches of soil, as that may disrupt its efflorescence ability to discharge excess moisture from the underlying twin V shaped cavities.

  - Since horizontal cavities lie in the mid and lower belly sections, part of the pole's lower surface must be visible for air circulation inside the pole. Moreover, pole fenestrations must also remain open for air to flow through fenestrations of other poles.

  - Since shallow roots may grow near the pole's base, they should only be excavated, and not more than three inches of root vegetation inside the pole's vicinity should be disturbed.

• Standard concrete electrical poles

  - Height: 8-12 m

  - Weight: 750 kg

  - Diameter:18-21 inches (457-533mm)

  - Material: Cement mix

• Maintenance

  - Strengthened poles made with PSC are more resistant to natural elements like wind, rain, and humidity, along with typical electrical issues like arcing and insulation failure. Regular inspection and surveillance are all, though necessary, to ensure that they are the most ideal poles for electrical use.

  - Other types of cement electrical poles, such as spun cement poles, may be more prone to damage due to electrical issues. The inspection and monitoring frequency may differ. A concrete electric pole under a region where lightning precipitation is more likely should have an increased frequency of inspection and monitoring to ensure the more critical lightning arrestors are in good condition. Lightning arrestors connected to the grounding system usually undergo monitoring frequently. Other components will be less frequently monitored but should be checked at least once a year.

Scenarios of 35kv concrete poles

35kv concrete electrical poles have wide applications in the energy, industrial, and telecommunication sectors.

• Power Transmission

  35kv concrete poles serve as backbone structures for high-voltage power lines that transmit electricity over long distances from power generation plants to substations. Using concrete over materials like wood provides greater stability and a longer life span because high-voltage power transmission often requires large, heavy conductors and significant line heights. Additionally, the durability and strength of concrete make it well-suited for supporting heavy transmission lines and withstanding the forces exerted by high-voltage conductors.

• Distribution of Electricity

  In areas where population density is high, concrete poles facilitate the safe and efficient distribution of electricity to residences and commercial buildings. They support lower-voltage distribution lines and help maintain a reliable power supply to urban areas. The durability of concrete poles is crucial in urban environments where space may be limited, and additional demands are placed on the electrical infrastructure.

• Renewable Energy Projects

  35kv concrete poles are also employed in renewable energy projects like wind farms or solar energy facilities to support the project's internal electrical infrastructure or the connection of the renewable energy source to the external power grid. Concrete poles offer a stable and durable solution for integrating renewable energy sources into the existing electrical grid.

• Telecom and Data Transmission

  In addition to electricity transmission, 35kv concrete poles can also be used for telecom and data transmission. They provide a sturdy and reliable platform for supporting telecommunication equipment, such as wireless communication towers, antennas, and fiber optic cables. Concrete poles offer the necessary stability and strength to support the growing telecommunication infrastructure required to facilitate high-speed data transmission and communication services.

• Street Lighting

  35kv concrete electrical poles may also be used for street lighting. Concrete poles used for street lighting are often designed to support multiple light fixtures, providing adequate illumination for roadways and pedestrian areas. Additionally, concrete poles offer several advantages for street lighting applications. They are highly visible in low-light conditions, enhancing safety and deterring criminal activity. Moreover, concrete poles are often equipped with additional features, such as decorative lighting fixtures or smart city capabilities, further enhancing their functionality in urban environments.

• Signage and Advertising

  Another application of 35kv concrete poles is to support signage and advertising structures. Whether informing, directing, or promoting, concrete poles offer a stable and durable foundation for displaying signs and advertisements in high-traffic areas. Concrete poles provide the necessary support and visibility for effectively communicating messages to the public. Additionally, concrete poles can be integrated with digital signage solutions, allowing for dynamic and interactive advertising possibilities.
