The famous cable manufacturer, ZMS Cable, announced the signing of an important cooperation agreement with K-Electric Limited, Pakistan's largest electricity company. According to this agreement, ZMS Cable will supply high performance STACIR conductors to K-Electric Limited to support its power grid modernization and expansion projects.
This cooperation aims to improve the efficiency and reliability of Pakistan's electricity transmission network. By adopting high performance STACIR conductors, K-Electric will be able to further optimize the electrical transmission capacity and stability of the system. The success of this project will provide important support to the construction of electricity infrastructure in Pakistan, marking an important milestone in the strategic cooperation of the two companies in the energy sector.
Context and Significance of Cooperation
Current state of the electricity market in Pakistan
1. Imbalance between supply and demand
The imbalance between electricity supply and demand has always been a major problem in the electricity market in Pakistan. According to data from the National Energy Regulatory Authority of Pakistan (A MUST), the country's electricity demand increases by approximately 7 % per year, but current production capacity cannot meet this growing demand. The electricity supply is constantly under tension, especially during the high temperature summer season, often leading to large-scale power outages.
2. Obsolete transmission and distribution facilities
Transmission and distribution infrastructure in Pakistan is seriously outdated, with high transmission and distribution loss rate. According to government data, transmission and distribution loss rate in Pakistan reached 18 %, which means that around a fifth of electricity is lost during the transmission and distribution process. This not only leads to instability in the electricity supply, but also increases the costs of electricity production.
3. Lack of funding
Pakistan's electricity market has always faced financing problems. The government has been unable to provide sufficient funds for the renovation and development of the electricity sector, and private investors are also reluctant to invest in this sector, which limits the development of the electrical industry.
Cooperation Destination Situation
Karachi, located in the Aden region of southern Pakistan, enjoys a subtropical desert climate, with high temperatures and little precipitation for most of the year. This intense heat makes living conditions difficult and leads to a high demand for electricity.. However, under high temperatures, performance of traditional drivers may decline or deteriorate. During periods of extreme heat, the transmission capacity of power lines is limited, which forces urban areas to apply power cuts to avoid overloads and line disconnections during periods of high demand.
Cooperation Details
For a country like Pakistan, which needs a stable electricity supply to support its economic development, Improving the reliability of the electricity network is crucial. To overcome electricity shortages and achieve sustainable development of the electricity market, Pakistani government and relevant organizations are continuously exploring and trying new solutions. The signing of this cooperation agreement is an attempt to resolve the problems in the electricity market in Pakistan. This cooperation aims to improve the electrical stability of the Karachi region by introducing a new type of conductor capable of carrying greater capacity and withstanding high temperatures, thus ensuring a stable electricity supply.
ZMS Cable will provide STACIR conductors high performance to help K-Electric Limited significantly improve the transmission capacity and overall reliability of its network. Although this cooperation may seem like a simple replacement, it has major importance for the reform and development of the electricity market in Pakistan.
“We are very pleased to have the opportunity to collaborate with ZMS Cable. We have high expectations for this cooperation and we have full confidence in the professional skills of ZMS Cable. STACIR conductors supplied by ZMS will greatly improve the stability and efficiency of our electricity network. »
“We hope to establish a long-term and strong cooperative relationship with ZMS, to meet future opportunities and challenges together. »
ZMS Cable Product Manager said : “Thanks to multiple collaborations, ZMS has successfully established itself firmly in the Pakistani market. Our products and technologies have been recognized by end users, thus laying a solid foundation for our future collaborations. This cooperation with K-Electric Limited allows our new drivers to gain an advantage in the Pakistani market and makes us a supplier for K-Electric Limited, paving the way for stable and long-term cooperation. We thank K-Electric for its trust and support, and we look forward to the success of future projects. »

Advantages of the STACIR Driver
Structure
The STACIR driver (Super Thermal Aluminum Conductor Invar Reinforced) is a high performance conductor with excellent conductive and heat resistance properties, able to operate stably in high temperature environments. Its structure includes :
Ultra-heat-resistant aluminum alloy : The outer layer is made of a heat-resistant aluminum alloy, which maintains good conductive performance even at high temperatures.
Aluminum clad steel core (AW) : The interior uses a soul in aluminum clad steel, providing high mechanical support while having good conductivity and corrosion resistance.
Performance Characteristics
High current carrying capacity : Its current carrying capacity is significantly higher than that of traditional conductors, approximately twice as high as that of ACSR conductors and 1,7 times higher than that of AAAC conductors, which significantly improves transmission efficiency.
Excellent high temperature resistance performance : Can withstand operating temperatures up to 150°C, or even more, thus avoiding losses and deformation of conductors at high temperatures.
Great mechanical resistance : The aluminum-plated steel core offers great mechanical resistance, allowing the driver to remain stable in harsh conditions such as strong winds, areas of heavy ice accumulation and major crossings.
Low line loss : Resistance variation is small at high temperature, which effectively reduces energy loss during transmission and improves transmission efficiency.
Corrosion resistance : Aluminum-clad steel core provides excellent corrosion resistance, suitable for humid and saline environments.
Installation facile : The installation method is the same as ordinary ACSR conductors, without requiring modification or reinforcement of existing pylons, which simplifies installation and reduces design time and costs.
High reliability : Tested on over 10 000 kilometers of lines, the driver demonstrated exceptional reliability.
