Select cable penetration seal module MCT module notes

As a new type of cable penetration seal, the cable sealing module has been widely used in many industries, but there are still many problems in how to select the cable sealing module. Kai Ente Technology (Dalian) Co., Ltd. as a professional supplier of cable seal modules, combined with long-term market service experience, is summarized below.
A, cable sealing module profile
The cable sealing module is also called MCT module, MCT blocking block, cable sealing, sealing block, variable blocking block, adjustable feeder window, cable penetration sealing device, cable wall seal, cabinet cable sealing, cable through the wall Boards and so on.
The cable sealing module is a type of cable penetration seal. It is mainly used to achieve the requirements of airtight fireproof and waterproof, and at the same time ensure the integrity of the object. Modular cable sealing system consists of four parts: cable sealing frame, cable sealing module, pressing device, and spacer board, supplemented with grease and installation tools.
The cable sealing module is made of environmentally-friendly neoprene rubber. The module consists of two shift blocks and a core rod. The cable diameter can be adjusted within a certain range. At the same time, solid modules are available for selection.
The cable sealing module was first applied to the shipbuilding industry in foreign countries and is now widely used in ships, marine engineering, petrochemicals, machinery manufacturing, power, communications and other industries. Cable gland module. The cable sealing module is the development trend of the cable penetration seal and has the following advantages: simple and quick design and installation, better sealing effect, low cost of subsequent maintenance changes, and beautiful appearance. Will replace the traditional fireproof package, fire blocking materials and other blocking methods.
Second, how to choose cable sealing module
1. Correct selection of suppliers
Select suppliers, should choose a professional supplier of cable sealing module, preferably the cable sealing business is the main business of the manufacturer. Manufacturers should have certain industry application experience to understand the market application of products. The current cable seal market is mixed, and the information released by a large number of distributors on the Internet has brought us difficulties in selecting suppliers.
The author believes that an excellent cable gland module manufacturer should have the following points. A. The cable gland module is its main business; B. The sound company qualification and stable office space are not just published on the Internet with a few pieces of information. Leave a contact method; C. There is an independent company website and product physical map, many companies stole other company's product map (or PS picture), in fact, there is no product and service capabilities; D. can provide customers with professional and complete CAD drawings And quotations, not just a simple random quotations; E. should have good communication skills with customers, provide reasonable advice on customer product selection and design, of course, this requires some practical experience.
2. The correct choice of products
The correct selection of products should pay attention to the following aspects:
2.1 Module selection: The module is divided into 30 mm long and 60 mm long, both of which are the thickness of the entire sealing device. Therefore, a 60 mm long module is generally used when the cable passes through cabin decks, cables, and other heavy objects. When the cable passes through a cabinet or other thin object, a 30mm long module is generally selected, and the entire sealing device is also thin and light.
2.2 Selection of sealing frame: The sealing frame is determined by the sealing module. Different sizes and quantities of modules determine the corresponding sealing frame. When passing through the cabin decks and walls and other objects, a 60 mm thick frame should be selected. The material is generally low carbon steel and stainless steel. It is recommended to select different frame materials according to different application environments. It is recommended to select the stainless steel frame, because the general cable seal module application environment is the outdoor or indoor and outdoor connections, generally more dark and wet or in the sun exposure. Once the sealing frame has the phenomenon of corrosion and rust, it will directly affect the performance and life of the sealed module, and at the same time seriously affect the sealing protection effect of the entire sealing device.
2.3 The material selection of the compression block and spacer board: General cable seal supplier, both the material of the compression block and the spacer board are available in stainless steel and low carbon steel. I do not recommend the choice of low-carbon steel compression blocks and spacers, because the difference between the two kinds of material cost is not great, but the service life is very different, do not lose because of small losses.
2.4 The use of grease: It is recommended to use the grease strictly in accordance with the instructions for installation and use of the product. Many times the workers are afraid of trouble. In order to improve the efficiency, the use of grease is not used or less, which actually affects the overall sealing effect of the sealing device.
2.5 About installation tools: General projects are not recommended. A project with a large project volume is recommended to use a compactor, and the puller will only be used during maintenance and renovation. Many manufacturers generally sell a full set of installation tools as an essential product to customers, which actually increases the customer's procurement costs.
With regard to reservations: In general, it is recommended to set aside 30-40%. Of course, special consideration should be given if the project is carried out in phases. In addition, it is not advisable to use solid modules as a reservation, because this can temporarily save some procurement costs, but the actual changes require secondary procurement, which is not only wasteful but also increases costs.
Third, follow-up maintenance and repair of cable sealing module
The cable sealing module should pay attention to periodic inspection to check whether the frame loosen due to external force or other factors; check the module for stress damage. The inspection period is generally 3 months.
