Product Description

The product shell is made of FRP, which is an anisotropic material, plus its formula and additives have a wide range of selectivity. According to the working environment and state of FRP, special flame retardant additives are added to make the FRP material have good resistance. flammability, explosion-proof, corrosion resistance, long life and other advantages. In the environment of -50C-+150ºC, it can still maintain good physical and mechanical capabilities, protection grade IP55, maintenance-free.

No.	Item			Inspection Area			Test result			Content
1	Structure inspection			The whole machine			Pass			1) The nameplate mark is in accordance with the standard provisions; 2) The structure size is in accordance with the drawings and standards.
2	Temperature test			Shell, gasket, joint, single core cable joint potting part			Pass			The maximum surface temperatures of the sample shell, gasket, joints, and single-core cable joint potting parts were 63.5°C, 62.4°C, 106.6°C, and 106.1°C, respectively. Note 1: The cross-sectional area of the test cable is 300mm^2.
3	Heat-resistant hardy test			Gasket, cement and single core cable joint potting part			Pass			The sample was placed in an environment with a relative humidity of 90% and a temperature of 90°C for 14 days, and was placed in an environment of 127.0°C for 14 days, then placed at room temperature for 24 hours, and then placed in an environment with a temperature of 30°C for 24 hours, and sealed after the test. There was no obvious change in the sealing part of the mat, glue and single-core cable joint.
4	Protest against the impact test			Shell			Pass			The shell withstands the impact energy generated by the test object with a mass of 1.0kg falling vertically from a height of 0.7m, and the result is no damaged.
5	Insulation dielectric strength test			relatively			Pass			1. Test voltage: 21000V; 2. Test time: 60s; 3. Test results: no breakdown, arcing, flashover phenomenon.
6	Enclosure protection class (IP) test			The whole machine			Pass			Level 4 waterproof test: use a pendulum pipe water spray test device with a total flow of 4.3L/min and a test time of 10min. After the test, check that there is no water in the sample. The interior is completely filled with no cavities, meeting the requirements of class 5 dustproof.
7	Introduce the device clamp test			introduction device			Pass			A tensile force of 720M was applied to the cable with a diameter of 36.0mm for 6 hours, and there was no displacement.
8	Surface resistance measurement			The sample piece			Pass			Surface resistance value is 6.58 x 10^8Ω.
