Underground Cable Laying Standards

There is no single universal standard for underground cable laying. Standards are dictated by national and regional regulations, the type of cable (power vs. data), the voltage level, and the specific ground conditions.

However, the fundamental principles and best practices are very similar across the globe. They are all designed to ensure:

1. Public Safety: Protecting people from electric shock.

2. Cable Integrity: Protecting the cable from mechanical damage, moisture, and chemical corrosion.

3. Reliability: Ensuring a long and trouble-free service life.

4. Future Identification: Making it easy and safe for future excavators to locate the cable.

Here is a breakdown of the standard practices and key parameters, often derived from major international standards like the IEC 60364 series, the US National Electrical Code (NEC), and the UK's BS 7671.

WAZIPOINT System for Urban Cable Laying

How WAZIPOINT SYSTEM Utilizes Perfectly in Underground Cable Transmission Lines Excavation Equipment Performance in Urban Areas?

While "WAZIPOINT" is likely a proprietary brand name for an integrated technology suite, the principles behind such a system are at the forefront of modern construction technology. Let's break down how a system like this, which typically combines high-precision GPS, GPR, and GIS, is utilized perfectly in the complex environment of urban underground cable excavation.

First, let's define what a "WAZIPOINT-type" system is in this context. It's not a single technology but a fusion of several key technologies:

Cable Pulling & Jointing Tools and Equipment

Cable pulling, Jointing, and Termination equipment play very important roles to ensure quality work to operate a safe and long-life operation. Cable pulling tools make for easy and safe cable laying, less cable sheath or screen damage/scarce, applying pulling tension correctly, and spacing cable in trench or duct properly. Cable Joint and Termination tools are very much special for cable jointing and cable sealing end termination.

How Use Cable Pulling Tools & Prepare Cable Trench?

Before laying cable, cable trench or cable duct must prepare as per site requirement. Cable ducts or trench measurements will not same for all, depending on the voltage rating, cable size, laying location, and other vicinity factors cable ducts or trenches' depth and width vary.

EXCAVATIONS SAFETY IN THE WORKPLACE

How Excavations Carry on Safely in the Workplace:   

Excavation and trenching are among the most hazardous construction operations. The Safety and Health Code should be followed strictly during Excavation and Trenching in the workplace. Trenching and excavation work present serious hazards to all workers involved. Especially in trafficked, crowded city areas and moreover in the rainy season is more hazardous and much more likely than other excavation-related accidents to result in worker fatalities. Excavation in soil movement and cave-ins should take special care. Other potential hazards include falls, falling loads, hazardous atmospheres, and incidents involving mobile equipment.
