CABLE LOCATOR
Cable Locator
Underground Utility Detection & Fault Locator Device for KSA & GCC Infrastructure Projects
Types of Cable Locators
Cable locators are divided based on their features, method of detection, and area of application:
1. Electromagnetic Cable Locators
Detect the presence of metal cables by electromagnetic signals that are either passive or induced.- Commonly seen in power, telecom, and metallic water pipeline lines.
2. Radio Frequency Cable Locators
- A radio frequency signal is sent through the cable for its detection.
- Suitable for tracing over a long distance.
3. Passive Cable Locators
- Pick up electromagnetic signals coming from active cables.
- Can be used for live power lines without making any connection to the cable.
4. Active Cable Locators
- Directly connect to the cable and a signal is applied for very accurate tracing.
- Highest precision for fault detection and mapping.
5. Fiber Optic Cable Locators
Conductive tracers help special transmitter units to detect fiber optic ducts.
Key Features of Cable Locators
High Accuracy – Detects underground utilities with minimal error.
Multi-Utility Detection – Power, telecom, water, gas lines.
Depth Measurement – Indicates approximate depth of buried utilities.

How a Cable Locator Works
Cable locators work based on the principle of electromagnetic induction:
Transmitter Connection
- A target cable or pipe is connected to the transmitter.
- The utility receives an electromagnetic signal as a result.
Signal Propagation
- The signal moves through the utility which has conductivity.
Receiver Detection
- The receiver senses the electromagnetic field.
- The location and rough depth are provided by visual or audio indicators.
Tracing
The operator uses the receiver to move on the ground in order to track the line of the cable or pipe.
Applications of Cable Locators in KSA & Gulf Region
Urban Construction Projects – Safe excavation around utilities.
Smart City Installations – Accurate mapping of fiber optic and power cables.
Municipal Water & Sewer Networks – Trace buried pipelines before maintenance.
Telecom and Data Centers – Identify and protect fiber optic conduits.
Highway & Road Construction – Avoid accidental utility strikes during civil works.
Industrial Plants – Locate underground power or process lines in complex layouts.
Advantages of Using a Cable Locator
Safety
This technique prevents accidental injuries as well as electrocutions when performed in a certain manner.
Accuracy
The underground services are located with extreme accuracy and the depth is measured correctly.
Cost Efficiency
Less accidental damage, consequently less repair cost and time also reduced on the project.
Regulatory Compliance
This technology provides an excavation safety in KSA & GCC which is up to date with municipal and utility standards.
Versatility
Electricity, water, sewage, gas, and telecommunications are some of the utilities that can be used with this technology.
Time-saving
This method is much faster than manual digging or using hit-and-miss detection.
Installation and Operation Guidelines
Prepare the Device
Charge batteries and check calibration.
Connect Transmitter
Connect directly to the target cable/pipe or use inductive clamp.
Select Frequency
Choose the frequency based on cable type and length.
Scan Area
Move receiver slowly along the surface to detect signals.
Trace Path
Follow visual or audible indicators to map the utility route.
Document Findings
Record depth, location, and utility type for GIS or project records.
Environmental Suitability
The cable locators that are engineered for the GCC region can endure:
- Very high temperatures (maximum of 60°C)
- Sediment and windstorms
- Moisture and saltiness in coastal areas
- Unskillful handling on building sites
- High standard devices keep detection precision and lifespan even in the most unfavorable situations.
Life Expectancy and Durability
Typical lifespan: 8–15 years with regular maintenance
Shock-resistant casing protects internal electronics
Replaceable batteries ensure continuous field use
Compliance and Safety Standards
Cable locators generally comply with:
IEC 61010 – Safety requirements for electrical equipment
ISO 9001 – Quality management in manufacturing
GCC Electrical & Utility Safety Regulations
EN 50518 – Utility locating standards in some cases
Best Practices for Using a Cable Locator
- Calibrate device on each occasion of utilization.
- Nearby power lines or metal structures should not create any interference, if possible.
- Ensure that the receiver's height above the ground is always the same.
- Document every result in GIS or utility maps.
- In case of underground conditions that are complicated, apply different frequencies.
Conclusion
The Cable Locator is a crucial device for modern infrastructure undertakings in Saudi Arabia and the Gulf area. Through accurate underground utility identification, it guarantees safety, compliance with regulations, and the economic viability of project execution. The equipment's wide-ranging uses in the areas of electricity, telecommunications, water, and sewage give it a vital role for contractors, engineers, and local governments. The use of a dependable cable locator not only secures the physical assets of the infrastructure but also avoids expensive breakdowns and increases the efficiency of the project.
