Cable sealing module
Due to the particularity of the marine environment, ships sailing at sea need to withstand the test of harsh environment, fire, gas, seawater, salt spray, corrosion and other risks. The sealing performance of pipeline and cable penetration systems is particularly important.
Ship cable sealing method

Common ship cable sealing devices can be divided into: traditional injection type, stuffing box type and new modular sealing device according to the structure.
Traditional sealing methods have many disadvantages, such as: increasing the burden on the hull, poor fireproof and sealing performance, and high maintenance costs in the later stage.
The most advanced technology on the market at present is the ship modular cable/pipe sealing system (Multi Cable Transit), referred to as MCT. However, the domestic market of this product has long relied on imports and the price is very expensive.
TST SEAL has always focused on the upgrading and transformation of cable/pipe modular sealing solutions for many years. The modular cable/pipe sealing system it produces can completely replace foreign brands in terms of performance, but the price is lower than that of imported products.

TST SEAL domestic modular cable sealing system

TST SEAL domestic modular cable penetration device is a product certified in the field of ships, which can achieve Class A separation. Its fire resistance level is divided into A-0, A-15, A-30, and A-60. In addition to fire resistance, it can also have functions such as sealing, electromagnetic interference prevention, grounding, redundant design, maintenance-free, and non-destructive disassembly and assembly.
1. Non-toxic and halogen-free
According to the non-toxic and safe product, it complies with the provisions of the EU RoHS Directive 2011/65/EU (RoHS 2.0) and its amendment directive (EU) 2015/863 standard restricted substances limit table; it does not contain halogen and complies with the halogen limit standard in IEC 61249-2-21.
2. Fire resistance level
The modular sealing system meets the A-0 and A-60 fire resistance levels in the “2010 International Fire Test Procedure Application Rules” (FTP Rules) standard; meets the fire protection requirements of R22/R23 category materials in the EN45545-2 standard, and meets the requirements of the HL3 dangerous level of fire risk; meets the 2h fire resistance level in the GB23864 standard; can provide the E150 fire resistance level in the EN13501-2 standard;
3. Sealing performance
Watertightness can reach the pressure level of sealing, depending on the model, it can meet the pressure sealing of different levels of 0.1MPa~0.4MPa. Airtightness can reach the pressure level of sealing, depending on the model, it can meet the pressure sealing of different levels of 0.05MPa~0.2MPa.
4. Protection level
According to international, European and national standards, it has passed the tests of high temperature resistance, low temperature resistance, impact and vibration resistance, humidity and heat resistance, UV aging resistance, ozone aging resistance and corrosion resistance; after vibration and impact according to IEC 61373 or GB/T21563 standards, the seal can reach the sealing protection level IP68; it meets the C5-M corrosion environment in ISO 12944-2 standard, that is, a very high marine corrosion environment.
5. Electromagnetic compatibility and explosion resistance
According to the requirements of GB/T12190-2006 “Measurement method for shielding effectiveness of electromagnetic shielding room”, it is tested in a wide frequency range of 14kHZ~18GHz, and its shielding effectiveness is 42~63dB.
Meet the technical indicators of Ex E ⅡC Gb and Ex E ⅡC Gc in IEC 60079 “Explosive environment”.
6. Standardized products support redundant design
Standard modular sealing products are suitable for various cable penetration and sealing conditions. The products can be combined and designed like building blocks, which is very flexible.
7. Flexibility generates economic benefits
The new penetration device supports lossless addition or replacement of cables. The installed penetration device can be opened, and the replaced or added cables can be connected and closed again, saving time and cost.
