Manufacturing Benefits of Over-Molded Cables Explained

Over-molded cables are extremely adaptable, functional, versatile, and favorable in a range of circumstances that occur on an oil rig. They can be customized for use under the guidelines of any design specifications. The cable ends are always protected because the pin connectors and wire are enclosed within a terminated shell.

an electric cable.


Since oilfield extraction companies can’t afford power delays or bad connectivity, over-molded make sure that operations are never disrupted. They are the most popularly used cable assembles in oilfield instrumentation today, and here’s more on that.

Other Features

Cable assemblies come with different kinds of thermoset or thermoplastic materials. Injection molding can be made to provide various mechanical properties that can be adjusted according to the oilfield conditions and environmental factors.

Oilfield infrastructure is complex and requires extra safety to prevent electrical (and other) hazards. Over-molded cables provide resistance against stress, strain, and abrasion that improves durability and strength under the most demanding work conditions. Such cables are also resistant to shock, repeated flexing, and vibration without permanent or lasting damage, preventing termination in the worst possible cases.

Manufacturing Process

The manufacturing process for over-molded cables follows a stringent routine that ensures that the result checks all quality controls. First, the cable assemble is put in a mold. Then, a thermoplastic or thermoset polymeric material is melted on high temperate until it has a fluid consistency. Dyes or colorants may or may not be added to the molten resin for aesthetic or functional customization.

Once it’s ready to be poured, it’s injected into the mold at a high-pressure setting and allowed to rest and cool. Once cooled, it solidifies, encapsulating the cable assemble into a shape of your choice with embedded brand names or logos.

Applications of Over-Molded Cables

Exposure to contaminants, reactive solvents, and the elements can increase the risk of accidents and hazards on off-shore rigs. Customizing the mechanical features of your cables can make work conditions better and safer. Over-molded cables allow for extensive oilfield applications in the oil and gas industry. Their resilience and reliability to operate in harsh conditions make them a win-win for oilfield instrumentation. Polyurethane is a thermoplastic that’s excellent to be used in rough conditions in over-molded cable assemblies. It’s resistant to aging, and weathering can therefore adapt to the harsh climatic conditions at sea.

If you’re looking for affordable but high-quality oilfield instrumentation, including over-molded cable assemblies, look no further.

How to Avoid OSHA Violations at Your Drilling Rig

Image
  The health and safety of workers in the oil and gas mining industry are major concerns. Exposure to hazards, extreme work environments, and accidents while operating heavy machinery means that oil/gas industry employees are at a higher risk of injuries and fatalities. As a result, the Occupational Safety and Health Administration ( OSHA ) has outlined certain precautions that help prevent accidents and keep your employees and worksite safe. Significant focus has been put on inspecting oilfield worksites, so you want to be prepared for any unexpected visits at your facility at all times. Staying prepared means that not only do you get to avoid fines and citations , but you also keep your workers protected. Let’s take a look at the top three violations on OSHA’s list, as well as the steps you can take to prevent them. 1. Inadequate Fall Prevention According to the National Safety Council, falls are among the most common hazards in the workplace, leading to approximately 50,000 severe i

Most Common Oilfield Instrumentation Issues

Image
Oilfield instrumentation  is a system of measuring, recording, and analyzing parameters such as temperature, pressure, and flow rate. It’s used to monitor the production of petroleum and natural gas wells. Here are five common oilfield instrumentation issues that oilfield operators should know about. Equipment Failure Equipment can either fail mechanically or electrically. The most common failures are due to power surges or lightning strikes. Electrical failure is one of the most common causes of oilfield instrumentation issues. They are caused by improper grounding or insulation issues with wiring in the wellhead. Mechanical failures  are usually due to wear and tear on moving parts caused by high-temperature environments or corrosion from corrosive chemicals in the wellhead. Lack of Communication Between the Wellhead and the Surface Any oilfield or gas field instrumentation is at risk of malfunctioning if the communication between the wellhead and surface is faulty. One issue that ca
